7 different tables below are an excellent manual for owners of boiler of Potterton brand. Each of them describes the possible problems of a particular model of boiler of this brand. Problems of some models can be identified with the help of an error code and can be fixed with the help of information from the tables. In other models, the problem can be identified by visual inspection of the boiler. Before call the service, conduct an independent examination and draw a parallel between identified problem ant the same one in the manual. Perhaps one of these tables will save your time and money.

Potterton Timer Control Instructions

Can anyone please help me with a question regarding the back up battery inside a Potterton EP 2002 controller which is 5 years old. The controller works fine but I lose all the settings whenever the mains electricity goes off. As we live in a country area this can happen 2 or 3 times a week sometimes.

Potterton Potterton 15 Boiler Troubleshooting

Problem	Possible causes	Solution
The radiators are cold.	The temperature set point for the heating is too low.	Increase the value with the CH temperature knob or if a room thermostat is connected, increase the temperature on the room thermostat.
The heating mode is deactivated.	Activate the heating mode.
The radiator valves are not open.	Open the valves of all radiators connected to the system.
The boiler is not working.	Check that the boiler is being supplied with power. Check fuses and switches.
Check whether the gas isolation cock is properly open.
If the property has a prepayment meter ensure it has sufficient credit.
The water pressure is too low (< 0.5 bar).	Re-pressurise the system.
The boiler is not working.	The temperature set point for the heating is too low.	Increase the value with the CH temperature knob or if a room thermostat is connected, increase the temperature on the room thermostat.
No demand for heating.	Ensure that timers & thermostats are calling for heat.
No power supply.	Check that the boiler is being supplied with power. Check the fuses and switches.
The water pressure is too low (< 0.5 bar).	Re-pressurise the system.
The boiler is indicating an error.	Press the Reset button. Correct the error, if possible.
The gas pressure is too low.	Check whether the gas isolation cock is fully open. Open the gas isolation cock.
Condensate drain blocked.	Check drain, especially any external runs in freezing temperatures.

Potterton Derwent Prestige plus Boiler Troubleshooting

Problem	Cause
Boiler does not attempt to light.	a) Check electricity supply is available to boiler and on/off switch is illuminated. The boiler has an integral fuse.
Control Box does not lockout.	b) Check the boiler is being called to operate. Thermostat calling lamp should be lit unless internal thermostat is satisfied or external control circuit is broken.
c) Check overheat cut off device has not operated.
d) Check power supply is available to control box (see wiring diagram). Replace box if faulty.
No Ignition Spark. Pilot does not Light. Control Box goes to lockout	a) Check ignition electrode continuity for earth fault.
b) Check power supply is available to ignitor during ignition period.
c) Check operation of ignitor. Replace if necessary
Ignition sparks Pilot does not Light. Control Box goes to lockout	a) Check gas supply is available at the pilot burner at the correct pressure.
b) Check gas supply is purged of air.
c) Check pilot injector
d) Check ignition electrode position.
Pilot Burner lights Control Box goes to lockout safety time	a) Check electrical supply polarity
b) Check earth continuity to pilot burner
c) Check pilot burner pressure is correct
d) Check there is no earth leakage on ionisation probe circuit.
e) Check ionisation probe circuit for correct flame current. This is achieved by connecting a DC micrometer in series. A reading of at least 7^A DC should be obtained. If this is obtained and the control box continues to lock out then replace the control box.
Pilot Burner Lights. Main burner does not light Control Box does not lockout	a) Check main burner gas cock is open.
b) Check electrical continuity to main gas valve
c) Check operation of gas valve and replace if necessary
d) Check control box. Replace if necessary
Pilot Burner Lights Main burner lights Control box locks out.	a) Check ignition of main flame is smooth and reliable.
b) Check voltage supply for interference.
