Troubleshooting Manual
Quick Fault Finding Procedure
When troubleshooting your Potterton Promax Combi boiler please follow the following logical fault finding procedure
- Electrical Safety Checks. Check the electrical circuits by testing short circuit, earth continuity and resistance to earth tests. Check correct electrical polarity.
- Electrical Supply. Ensure that the boiler has electrical supply correct to 230 V.
- Gas Supply. Check the boiler has gas supply and that it has been purged. Ensure the boiler has an inlet gas pressure of 20 mbar at the gas valve.
Warning: Use only qualified Baxi Customer Support to work on Potterton gas boilers. All Baxi registered installers carry a BAXI identification card and have a registration number.
- Filling the Heating system. Ensure that the boiler is full of water and charged to 1.5-2.0 BAR.
- Control. Ensure main on/off control is set to ‘on’
- Temperature. Set the heating temperature to the maximum setting.
- External Controls. Check that the external control display is calling for heat. Ensure that the boiler’s anti-cycling economiser is not engaging.
In an Emergency
If you suspect water or gas leak turn off the electrical supply and turn the selector switch on the facia box to the Off position, turn off the gas supply at the meter immediately and at the isolating valve on the boiler if possible. Call your customer support immidiately and request boiler specialist as soon as possible. Contact your Gas Supplier immediately.
Servicing your Appliance
For safety and economy reasons your boiler should be serviced annually. Your boiler specialist will be able to advise you. Proper ventilation should be checked periodically and electricity supply must be earthed. Standard 230V ~ 50Hz supply is required for all Potterton boilers. Never hang flammable items over the boiler.

Reseting Potterton boilers
All Potterton boilers can be reset. Resetting boilers with LED display should be performed when LED is showing continuous or flashing red. Normally it occurs when the boiler fails to light or the boiler is actually running, but the gas is turned off. To reset you need to press the reset button for a 1-10 seconds, after this LED will stop flashing and the boiler will attempt to re-light.
Attention!!! When LED display is flashing red very fast then the control is in remote diagnostic mode. The boiler will not work in this mode and will need to be reset again. You will need to press the reset button for 10 seconds, the LED will flash Orange once then return to normal operation.
In cases boiler doesn’t reset, check the error codes above and phone a boiler specialist to remove fault.

Initial steps
- Before starting to work on Potterton boilers turn off the thermostat knob to O (Off) on the control panel cover (hinges down)
- When removing and replacing any parts that involve draining the system, close the boiler isolation valves and then drain the boiler using the presure gauge connection. It is forbiden to use the safety valve to drain the boiler. For all Dv Models: when removing and replacing any parts that involve draining the system, the manual lever is on the left hand side of the diverter valve must be moved to the ‘MID’ (manual override) position. Return it to its original position after the system has been filled and vented. Non-Dv Models with external diverter valve: When removing and replacing any parts that involve draining the system, it may be necessary to move a lever on the diverter valve, see manufacturers instructions for the particular valve. Return it to its original position after the system has been filled and vented.
- Always allow the boiler to cool and isolate the electricity supply.
- Always turn off the gas at the gas service cock.
- When removing any items containing water (Hoses, pipes etc) make sure they do not spill on electrical components.
- Always replace consumable parts like o-rings and gaskets with new parts
- Always conduct electrical check such as polarity, continuity and resistance to earth with a multimeter before and after any work
Warning! Always test for gas soundness after completing any exchange of gas carrying components and carry out functional checks of controls.
Replacement of any component requires the removal of the outer case front panel. To remove it follow steps below:
1.Open control panel cover, remove the two screws (one each side) securing the control panel to the case side panels.
