Master Troubleshooting & Diagnostics Matrix
| Error Code / Indicator | Symptom / Meaning | Possible Cause | Step-by-Step DIY Fix | Suggested Actions |
|---|---|---|---|---|
N/A | Heating ignition sparks can't be heard, or are more than a second apart | — | Fit a new battery in the automatic ignitor. | DIY Safe |
W 42 H | Truma CP plus control panel displays a warning icon | An operating parameter of the heating system has reached an undefined status; the device continues to operate. | Select the warning icon using the adjusting knob/pushbutton, then press it again to read out the warning code shown (format: W for Warning, a code number, then H for Heating). Once whatever caused it has been sorted, press the knob/pushbutton once more to return to the normal setting mode. If it hasn't been sorted, use the reset button instead - the panel will stay in its warning state and keep the icon showing, though every other connected device carries on working as normal. | DIY Safe |
E 41 H | Truma CP plus control panel immediately goes to Malfunction mode and displays the Malfunction error code | A genuine malfunction has occurred in the heating system (format: E = Malfunction, code number, H = Heating). | Once the underlying cause is sorted, press the adjusting knob/pushbutton and the affected device will restart on its own. If it isn't sorted, use the reset button instead - because of a short internal lag in the connected equipment this can take a few minutes, and the panel may drop back into Malfunction mode again if the fault's still there.
Every other connected device keeps working throughout. | DIY Safe |
N/A | FrostControl safety/drain valve indicates a risk of sub-zero temperatures | The FrostControl valve has detected a risk of sub-zero (freezing) temperatures. | The valve automatically drains the boiler's contents via the drain outlet - no action needed unless you want to prevent the automatic drain, e.g. by keeping the installation area heated. Intermittent pressure equalisation automatically takes place via the safety valve whenever the system pressure gets too high. | DIY Safe |
Frequently Asked Questions
Q: How do I fill the boiler?
Shut the cold water intake's outlet valve by setting its lever horizontal, switch the power on at the control panel, then open a tap and leave it running until the air's been pushed out and water starts flowing, then close the tap again.
Q: How do I empty the boiler?
Switch off the power at the control panel, open the kitchen and bathroom taps, then open the boiler's own outlet valve by setting its lever vertical and let it drain straight outside.
