FAULT FINDING

T FINDING F

T FINDING

Check all connections to PCB.

If no fault found, replace PCB

Reset the overheat 'stat. Set control

'stat to maximum. Allow the boiler to

reach temperature - if the overheat

'stat trips again, measure flow

temperature.

If above 90

C replace control 'stat.

If below 90

C replace overheat 'stat.

START

Is the mains on neon '

3' illuminated?

YES

Is there a live supply on EITHER

terminal of overheat 'stat?

Is the ignition electrode sparking?

YES

Check mains supply and fuses.

Check programmer and system

thermostats are all ON.

Check that boiler plug and socket

are OK and fully connected.

Check that the boiler thermostat is

set at maximum and the mains on/off

switch is ON. Is the fan turning ?

Replace the sensor

Check connections and leads to

pressure switch. If no fault found

change pressure switch.

Check all connections to PCB.

If no fault found change PCB.

Check pressure switch sensing

pipes for blockages, bad connections

and reversed connection.

Check S trap for blockage.

Is pressure difference at switch

greater than

0.9 mbar?

Change

fan

YES

Change

pressure switch

Is the boiler casing

correctly fitted?

Does the pilot light ?

YES

Does the spark

stop after the

pilot is lit?

Is there a gas

supply to the

boiler?

Is the pilot

injector blocked?

YES

Replace

gas valve

Is there a supply on terminals

of main gas valve?

YES

Is there a supply on the fan

connector at PCB ('Molex'

marked 'FAN'?).

YES

Check the

polarity of the

mains supply.

Check the

continuity of

the ignition

lead from

connector to

electrode.

Does the

spark now

cease when

gas is lit?

Ensure pilot and

main gas valve

leads are not

crossed over.

Is there a supply

voltage at pilot

gas valve?

Is there a live supply on the red

lead to the pressure switch?

Is there a regular spark from

tube 'SG1' on the PCB?

Can the overheat 'stat

be reset when the

system is cold ?

YES

Replace fuse BUT, before

attempting to start boiler, check for

short between live and neutral,

also between live and earth, on all

items plugged into PCB

Check all connections to PCB.

If no error found, replace PCB.

Remove the sensor

(NTC) from the PCB.

Is the fan turning ?

YES

Has the fuse blown on PCB ?

Is there a live supply on the

violet lead to pressure switch?

Is there a supply at the fan?

Replace the overheat thermostat

Does main burner

cross-light from pilot?

Is the main burner

injector clear?

Replace main gas

solenoid valve

Check gap at ignition electrode.

Check electrode and lead are

undamaged and not close to

earthed metalwork.

YES

Change

fan

YES

Rectify bad
connection

YES

Check PCB by substitution

Is there a live supply on

BOTH terminals of limit stat?

YES

Change limit thermostat

Is there a live supply on BOTH

terminals of overheat 'stat?

YES

If condensate pump kit fitted check

continuity of C-NC terminals

Check for condensate blockage

Is there a live supply on BOTH

terminals of the flue protection stat

YES

Reset flue protection thermostat

YES

Change flue protection thermostat
