85 L.....F.....(FLAME DETECTION ERROR)<br />
60<br />
If the boiler reset button is<br />
pressed does the boiler ignite for<br />
a short time then extinguish?<br />
YES<br />
Check the detection electrode and<br />
associated harness for:<br />
continuity, visual condition, position<br />
(Refer to Frame 59).<br />
Replace as necessary.<br />
Check the ignition<br />
electrode and associated<br />
harness for: continuity,<br />
visual condition, position<br />
(Refer to Frame 58).<br />
Are these functioning<br />
correctly ?<br />
NO<br />
YES<br />
NO<br />
FAULT FINDING<br />
Is gas pressure available at<br />
the boiler inlet ?<br />
YES<br />
Is 200V DC supply available<br />
at the gas valve ?<br />
(see Note)<br />
YES<br />
Check spark generator and associated<br />
harness for continuity and visual condition.<br />
(Refer to Frame 60).<br />
Are these functioning correctly ?<br />
86 L.....E..... or H.....E..... (PCB ERROR)<br />
YES<br />
NO<br />
NO<br />
Check gas supply<br />
and rectify fault<br />
Check gas valve<br />
wiring for<br />
continuity<br />
Replace PCB<br />
Replace spark<br />
generator<br />
Replace gas valve<br />
Note. Due to the wave form of the rectified voltage, the reading will vary depending on the type of meter used to<br />
measure the value (some may measure the possible peak voltage of 339V). In general terms a reading greater<br />
than 150V indicates that the correct voltage is supplied to the gas valve. As an alternative to a meter, a mains<br />
voltage checking device may be used. E.g. an electrical screwdriver or mains tester.<br />
Check for excess voltage between neutral<br />
and earth. Is the value below 50V?<br />
YES<br />
LE ONLY: Check continuity of OH<br />
thermostat. Is this correct?<br />
YES<br />
HE ONLY: Check earth wire is connected to<br />
detection lead. Is this correct?<br />
YES<br />
Check all earths for continuity<br />
YES<br />
Internal fault within the PCB<br />
Replace ignition electrode and<br />
associated harness as necessary<br />
NO<br />
NO<br />

NO<br />
Press and hold reset button for 2<br />
seconds. Does boiler operate<br />
correctly?<br />
NO<br />
Turn boiler off and wait for 5<br />
seconds. Turn boiler on.<br />
Does boiler operate correctly?<br />
NO<br />
Replace PCB<br />
NO<br />
Check syphon and condensate drain<br />
pipework for blockage<br />
Check earth connection to the boiler. If value is still in<br />
excess of 50V consult a Qualified Electrician to check the<br />
household electrical supply and circuitry<br />
Correct wiring or replace thermostat<br />
Correct wiring or replace detection lead<br />
Correct connections<br />
