75 H......F........

(FLAME DETECTION - SHORT CIRCUIT ERROR)

Replace flame detection electrode

Is there continuity between the 2 terminal pins ?

Replace PCB.

76 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.

Check resistance, using a suitable multimeter

connected across the thermistor terminal pins.

Are thermistor values correct ?

Inspect heat

exchanger for

blockage or damage

in the flueways.

Clean or replace as

necessary

Replace thermistor

77 H......n........

(PHASE REVERSAL ERROR)

YES

Remove flame detection electrode terminal from PCB.

H9/L9 (FLUE GAS OVERHEAT)

YES

Check wiring to the boiler for

reversed live and neutral

Foot Note: POLARITY CHECKS

Use a multimeter (set to measure 230 V AC or more), connecting the black lead to a reliable

Earth

point

(not Neutral for this

particular test).

You should find 230 V on terminal L and zero (or a small reading) on terminal N.
N.B.

Some meters may trip residual current devices during this test.

Note.

With V9 Primary Control PCB, overheat LA/HA or

H9/L9 when reset will display 3 horizontal lines and will
not attempt to re-fire until the temperature in the heat
exchanger drops below 50
