In any case Chris you have as much if not more difficulty with these devilish machines!
Chris's last job:-
""""I had to explain it to he who was paying so have it write down:
Wouldn't have believed it possible on such a simple thing. Only one of the visits was "my fault" I think.
1st visit Weds "Not lighting properly" so I took a diaphragm. The black plastic disc the diaph pushes was broken up. Didn't have one of those.
Bought service kit
2nd visit, Thurs changed that, and the thermocouple. The tc solenoid was dud. Have never changed one of those, didn't have one.
Bought solenoid.
3rd visit, Fri before Xmas changed that, and piezo ignition & electrode cos it wouldn't light pilot properly, and it ran fine for a week.
Then (Today, 2nd Jan)No hot water. Report first came that the fan was running (slowly), so the gas valve must be sticking to break the plastic disc, according to chaff.
Searched country, found only 2, miles away. Gloom.
Wondered if punter was turning the knob to "run" so rechecked ... and
Report came that it was dead, and fan not running. So, knowing the APS can blow fuses on those, I bought one. (About £100 retail!)
This takes time!!
4th visit Put fuse in, fan ran, but lotsa sparks.
Parts on pcb blown to bits.
Took APS back to supplier for credit.
5th visit, took a "New" unused pcb I've had for a while - it was my father-in law's...
It worked a bit, then it didn't.
Spent an hour with a soldering iron trying to get one board working from the old and the new, but the circuit diagram in the manual is WRONG and there seemed to be more than one fault on the unused pcb. Late, gave up, went home.
6th visit, took a new new pcb.
Working in London isn't so bad. Say there are 8 Landlord Certs, £70 each. Fiver for a travelcard. Charge 'em all £5 parking and £8 Congestion Charge, make £99 for going to work, making £659 for the day and home in time for something really exciting on telly.. """
I would never get away with charging £8 congestion charge eight times for one day !!!
