N/A | No 230V output from the PSU - the lead connecting site to vehicle isn't plugged in. | The lead connecting the site to the vehicle isn't plugged in. | Check and plug in the lead - see the 230V mains connection and safety-checks section, part C. | DIY Safe |
N/A | No 230-volt output from PSU: RCD switched off | RCD switched off | Reset the RCD following the steps in the 230V mains connection and safety-checks section, part D. | DIY Safe |
N/A | No 230-volt output from PSU: RCD not operating correctly | Equipment or wiring fault | Check the supply polarity - if the RCD still won't reset, contact your dealer, since it's likely an equipment or wiring fault. | DIY Check / Tech Fallback |
N/A | No 230-volt output from PSU: MCB switched off | MCB tripped or switched off | Reset the MCB by switching it OFF (down) then back ON (up); if it keeps tripping, contact your dealer, since it's likely an equipment or wiring fault. | DIY Check / Tech Fallback |
N/A | No 230V output from the PSU because the site's own supply is missing or inadequate. | Site supply issue | Contact site Warden for assistance. | Professional Intervention Required |
N/A | No 230-volt output from PSU: Another fault | Unspecified fault | Contact your Dealer. | Professional Intervention Required |
N/A | The PSU's reverse polarity light is on because the mains supply is reversed. | The live and neutral supply have been swapped or crossed over. | The reverse-polarity light comes on if the live and neutral feeds have been swapped over. That usually points to a problem with the site's supply or the cable connecting it to your vehicle. Because the light assumes a UK-style supply (neutral earthed at the substation), it can light up with no actual fault when used abroad - if that happens, ask the site warden for advice. | Professional Intervention Required |
N/A | The control panel shows no display at all. | Power or connection issue | Check the batteries and fuses, and confirm the PSU isolate switch, charger switch, and mains supply are all on. Check the cable connecting the control panel to the PSU. If that doesn't help, contact your dealer. | DIY Check / Tech Fallback |
N/A | 12V Power turns off | Battery protect feature operated, over voltage protection activated, or engine started | The battery protect feature has stepped in to protect the vehicle and/or leisure battery (see the Leisure Battery guide, section C). Alternatively, over-voltage protection may have triggered, which the control panel will show as a warning - most often caused by the solar panel, so check the regulator's connections and settings. Or, the engine has started and everything's been disconnected automatically to meet EMC rules (see 'Operation while driving'). | DIY Safe |
N/A | Control Panel locked / erratic function | Handling instruction issue or control panel software crash | Follow the control panel's own handling instructions - its software may have crashed. Reboot it by switching off the PSU isolate switch, waiting 30 seconds, then switch it on once more. Check with your dealer whether a software update is available. | DIY Check / Tech Fallback |
N/A | No 12-volt output from PSU | No 230V supply, charger off, battery not connected, power button off, flat battery, blown fuse, equipment switched off | If there's no 230V supply, work through each of the following: is the charger switched on (it should light up when it is)? Is a charged battery actually connected? Is the control panel's power button switched on? Check whether the battery is flat or its fuse has blown (recharge/check fuses/check voltage reaches the battery). Confirm every fuse is present, intact, and correctly rated. Make sure equipment is powered on and plugged into the 12V supply. If none of that resolves it, contact your dealer. | DIY Check / Tech Fallback |
N/A | Leisure battery voltage low warning on control panel | Control panel power on, leisure battery selected as the active battery, and voltage level falls below 10V. | A message appears on screen along with a 60-second audible beep. | DIY Safe |
N/A | Leisure battery voltage very low warning on control panel | Control panel power on, leisure battery selected as the active battery, and voltage level below 9V. | A message appears on screen with a 60-second audible beep. If nothing's done within 30 seconds, the system cuts the power to stop the battery discharging too severely - this is an emergency cut-off, so under normal use keep the battery at 11.5V or above. It only covers leisure equipment controlled by the control panel's power switch, not equipment that's permanently connected. | DIY Safe |
N/A | Leisure battery voltage high warning on control panel | The control panel's power is on or off, the leisure battery is currently the active one selected, and its voltage has climbed above 15V. | A message appears on screen, and the control panel beeps repeatedly while the power switches off automatically - the beeping continues until the fault clears. | DIY Safe |
N/A | Vehicle battery voltage warning on control panel | The same low/very low/high voltage conditions as the leisure battery warnings above, but for the vehicle battery when it's the one selected - its low-warning threshold is 10.9V. | Same on-screen message and audible beep behaviour as the leisure battery voltage warnings. | DIY Safe |
N/A | Engine running message on control panel | The engine is started, so the system power is turned off. | A message appears on screen reading 'engine running'. | DIY Safe |
N/A | Mains lead (hook-up cable) still connected/plugged in warning on control panel | The engine's been started with the mains cable left plugged in and the charger still switched on. | A message appears on screen, and the control panel beeps repeatedly until the hook-up lead is unplugged. | DIY Safe |

N/A | The electrical system shuts down by itself randomly. | Over voltage. The Sargent system detects a voltage higher than 15V and shuts down, commonly caused by a faulty solar regulator or a fault with the mains charger. | To check if your solar regulator is faulty, determine if the random shutting down only happens during the day when it is sunny and the solar regulator is active. You can disconnect the solar input from your system, or cover up the solar panel to see if the problem stops occurring. Alternatively, you could measure the voltage coming out of the solar regulator, though this can be hard to pick up because the output can fluctuate depending on shading from clouds. To check if your charger is faulty, note that if you have a fixed voltage charger the voltage should be no higher than 13.8V. If you have a PX300 installed, visit the PX300 product page to find a downloadable attachment to check the operation of the charger. | DIY Safe |
N/A | Battery is overheating and showing symptoms of being overcharged. | A failed cell within the lead-acid battery (turning it effectively into a 10V battery, causing it to draw more current and overheat under normal charge voltage). | Check the battery for a failed cell. If suspected that the charger rather than the battery is at fault, consult the article 'My PX300 charger isn't working correctly?' for further troubleshooting. | DIY Safe |
N/A | Lithium battery has entered Deep Sleep mode (DSLP) with State of Charge reduced to 0% and output switched off. | The battery State of Charge has reduced to 0%. | Re-charge the battery as soon as possible to avoid reducing lifespan and performance. If the battery is in Deep Sleep mode, the 'lithium wakeup' feature of the Sargent PX310 charger may be able to wake the battery and start charging as normal, or apply a fixed voltage of 12V to 15V briefly across the terminals. | DIY Safe |
N/A | Lithium battery has entered Under Voltage Protection mode (UVP) because internal cell voltage dropped below 2.5 volts per cell or terminal voltage fell below 10 volts, switching off power from the cells. | Critical low internal voltage of battery cells due to deep discharge. | Re-charge the battery immediately. Attach a fixed voltage charger to recover the battery cells to a point where they can switch back on (2.8 volts per cell, i.e., 11.2 volts in total for four cells). Depending on the state of discharge, this may take up to 30 minutes. | DIY Safe |
N/A | PX300 charger isn’t working correctly | — | Navigate to the PX300 product page via the link provided, locate and download the attachment, and follow the instructions within to test the output voltages of the PX300 and ensure the charger is working correctly. | DIY Safe |
Frequently Asked Questions
Q: What happens when the Sargent control system detects the battery State of Charge falls to 15%?
The control system will first issue an alert on the control panel screen to warn the user that the battery requires re-charging.
Q: What happens if the battery is not re-charged and the charge reduces further to 5%?
The control system will alert again, then power off all switched circuits to avoid further discharge. Note that any circuits powered directly from the battery will still be active and consuming current.
Q: How can I extend the lifespan of a Sargent lithium battery?
Avoid frequent deep discharges and maintain a partial state of charge, ideally between 40% and 80%. Do not rely on Under Voltage Protection (UVP) as a signal for when to charge the battery.
Q: I would like to fit a Lithium battery
Most Sargent systems have a Battery Charger like a PX300 or PF200 connected to the system. If your vehicle has another charger fitted, please consult the manufacturer's manual to check its compatibility with Lithium batteries. The PX300 charging profile is suitable for many Lithium batteries designed for the leisure industry that are fitted with an internal Battery Management System (BMS).
You can find a downloadable attachment detailing the charging profile and voltages on the PX300 product page, and you will need to ask the battery manufacturer of your choice if the PX300 charger would be suitable for their battery. Sargent systems fitted with a PX300 are: EC328, EC400 Series, EC500, EC600, EC700, EC800, and EC400+.
If your system is NOT fitted with a PX300 then your charger will have a fixed voltage of 13.8V and this is normally considered to be unsuitable to fully charge a Lithium battery. You will also need to consider if you need to install a DC-DC charger when changing your battery to Lithium to limit the charging current.
Q: I would like to fit a different AGM battery
Whilst we do not recommend any specific make or model of battery, the PX300 charger used in systems including the EC400/EC400+, EC500, EC600, EC700, EC800, and EC328 is compatible with the majority of good quality AGM batteries available in the UK. The charge profile of the PX300 is shown in the instruction manual attached below.
If you are in any doubt as to the fitment of a battery you should confirm with the battery distributor or manufacturer that the PX300 charge profile is suitable.

N/A | No water flows from any tap even though the pump is running. | Could be an empty freshwater tank, the pump wired in reverse, a disconnected inlet or outlet pipe, kinked pump pipes, a blockage in the pump's inlet or outlet pipe, a blocked pump filter, or an air leak in the pump's suction line. | Check the freshwater tank level; check the wiring against the pump manufacturer's instructions; check the connections and the pipe run; look for blockages starting from inside the freshwater tank; dismantle and clean the filter per the pump manufacturer's instructions; and check the condition of the pipe and its joints between the tank and the pump. | DIY Safe |
N/A | Pump does not run | Could be the pump wired incorrectly, a blown pump fuse, a disconnected battery, a seized or overheated pump, a failed pressure sensing switch, faulty contacts, or faulty wiring connections. | Refer to the pump manufacturer's instructions; check the wiring and replace the fuse with one of the correct rating; check all connections; follow the pump manufacturer's servicing instructions; confirm the plug and socket contacts are clean and making good contact; and check the wiring connections. | DIY Safe |
N/A | Water flows from the cold tap but not the hot one. | Could be a blockage in the hot pipeline, kinked heater inlet/outlet pipes stopping flow, a failed or blocked hot tap, or a jammed heater non-return valve. | Disconnect the pipes and inspect them, check the routing and re-route if needed, disconnect and inspect the tap, or arrange service attention. | DIY Check / Tech Fallback |
N/A | Water flows from the hot tap but the cold tap's flow is reduced. | Could be a kinked cold water pipe stopping flow, a blockage in the cold pipeline, the cold tap not connected, or the cold tap failed or blocked. | Check the pipe routing and reroute if needed, disconnect the pipes after the first connector and check through to the tap, refer to the installation instructions, or disconnect and inspect the tap. | DIY Safe |
N/A | Both the hot and cold taps have reduced flow. | Could be low battery condition making the pump run slowly, newly-fitted taps restricting flow, a pump needing servicing, a partially blocked pump or in-line filter (where fitted), a kinked pump outlet pipe, or a water leak. | Check the battery's state of charge (see the electrical supply note); disconnect the taps and confirm they have at least a 1/4 inch (6.3mm) bore; follow the servicing instructions for the pump; clean the filter and take it apart if that's needed; check the pipe routing and reroute if necessary; and check every water connection. | DIY Safe |
N/A | Reduced flow from either tap | Could be a kinked pipe restricting flow, or a mismatch in tap bore sizes. | Check the routing and reroute if necessary, and make sure the taps match in bore size. | DIY Safe |
N/A | The pump motor runs steadily and won't stop. | The battery voltage may have dropped too low (under 10.5V), or the container may have run dry. | Adjust the switch and/or recharge the battery, and check every connection in the pipework. | DIY Safe |
N/A | The space and water heater won't light (water heater only). | No gas; Air in pipe | Check the gas level in the cylinder, confirm the cylinder valve and gas taps are on, purge the system, and refer to the water heater manufacturer's instructions. | DIY Safe |
N/A | The PSU's reverse polarity light is on while running from a generator. | Certain generator types centre-tap their earth connection instead of earthing neutral directly, leaving both neutral and live conductors sitting around 110V above earth. | Seeing the reverse polarity light while running a generator is a normal quirk with certain generator types. Rather than earthing the neutral conductor directly, this type of generator taps into the earth connection at its centre point instead, leaving both the neutral and live conductors sitting around 110V above earth - and that 110V difference is what lights the neon polarity indicator. It's usually still safe to keep using the generator, but check its own handbook for confirmation. | DIY Safe |

N/A | Waste water level full warning on control panel | The pump's on and the waste water tank is full - only relevant where an on-board tank is fitted. | A message appears on screen along with a 60-second audible beep. | DIY Safe |
Frequently Asked Questions
Q: How do I adjust the pressure switch setting on a Truma/Flo-Jet pump?
Begin by removing the cover cap from the pump's end so the pressure adjusting screw is exposed. Don't move it more than a quarter-turn either way from the factory setting - clockwise raises the cut-out pressure, anti-clockwise lowers it. There's a second screw below the cover cap held with threadlock - leave that one alone.
You may need to remove the pump entirely to reach it: drain the water system first, then pull the blue taps out at right angles to the pipework and lift the pump clear.
