93 H.....4.... (DRY FIRE THERMISTOR ERROR)

Check wiring for continuity from the

PCB to the dry fire thermistor

Can the fault condition be reset by switching off

the mains supply to the boiler ?

Is the system filled and vented and

all isolation valves open ?

Is the pump operating correctly?

Ensure flow through system.

Are thermistor values correct ?

Replace PCB

Replace thermistor

Fill and vent the

system and open all

isolating valves

YES

Are thermistor values correct ?

Inspect heat

exchanger for

blockage or damage

in the flueways.

Clean or replace as

necessary

Replace thermistor

95 H......n.....

(PHASE REVERSAL ERROR)

Check wiring to the boiler for

reversed live and neutral

YES

94 H......F.....

(FLAME DETECTION ERROR)

Replace flame detection electrode

Is there continuity between the 2 terminal pins ?

YES

Remove flame detection electrode terminal from PCB
