| Error Code / Indicator | Symptom / Meaning | Step-by-Step DIY Fix | Suggested Actions |
|---|---|---|---|
N/A | Water pump will not run (Water system) | Check contacts in plug and socket are clean and making contact. Check wiring connections. | DIY Safe |
N/A | Water pump cycles on/off with tap closed (Water system) | Check for air or water leaks in taps and piping. Re-adjust pressure switch. | DIY Safe |
N/A | Water pump motor runs steadily and will not stop (Water system) | Check that there is water in the container. Battery voltage may be too low (at or below 10.5 volts). Adjust pressure switch and/or recharge battery. Check all connections in pipe-work. The Whale Tiptoe Pump can be fitted in-line with the submersible pump and used as a manual back-up. | DIY Safe |
N/A | Water pump doesn't switch off when taps are closed, or pulses on/off when taps are fully open (Water system) | Readjust the pressure switch: with the system full of water and all taps closed, turn the adjusting screw clockwise until the pump comes on; open the tap furthest from the pressure switch until flow is smooth then close it; turn the screw slowly anti-clockwise until the pump stops, then a further half turn (180 degrees) anti-clockwise; check operation on all taps individually. | DIY Safe |
N/A | Water pump runs continuously even with taps closed (Water system) Possible Cause: Present voltage is significantly lower than when last adjusted, or the water container is empty - risk of pump failure and a flat battery | Re-adjust the pressure switch or refill the water container. | DIY Safe |
N/A | Water pump does not run at all, fuse not blown, connections intact (Water system) Possible Cause: Most likely cause is excessive continuous running | Replace the pump and readjust the pressure switch. | DIY Safe |
N/A | Water pump runs intermittently ON, OFF, ON, OFF - pulsing flow from tap, or cannot hold a constant water temperature (Water system) Possible Cause: Present voltage is significantly higher than when last adjusted | Readjust the pressure switch; if the problem persists, add a Whale Surge Damper. | DIY Safe |
N/A | Water pump runs very noisily but does not pump water (Water system) Possible Cause: Pump is air-locked after the water container was refilled | Unplug the pump from its socket to let it flood, then reconnect. Always unplug the pump before placing it in the container when refilling, then reconnect. | DIY Safe |
