Geoff,

I have a Wickes Combi 2000 (a re-badged Halstead Quattro)- the boiler goes
through the normal ignition sequence when there is a call for heat (either
DHW or CH) but whilst the burner ignites, the flame never goes to maximum.

The DHW and CH thermistors appear to be operating normally.

OK

There is no output from the driver board (a Honeywell 4115B 1168, Halstead
part 500563)to the Modureg.

You are looking for up to 28v I take it

The solenoid is not open circuit and the burner
ignites fully when the spindle on the Modureg is pushed in by hand.

The manufacturers fault finding charts suggest that the driver board is
replaced.

If the main valve is operating and the sensors are OK, then that would
be the logical conclusion


I have removed the board - there are no obvious blown components, cracked or
shorted tracks. I think it possible that it might have got splashed with
water but there is no evidence of this.

Do you think that replacing the board will likely solve the problem?

From what you have said above, it sounds like it

Electronics doesn't always die with a bang


If so, do you have a spare board in stock?

I think I have one


If you have, can I drop in to the unit and swap the board for a recon
tomorrow? (Any chance of a guided tour if you aren't too busy?)

Give me a ring - 01923 229224


If I don't get a reply tonight, I'll try calling you tomorrow.

Many thanks,
Adrian Berry
