Catch up of some recent jobs, are you even a proper gas engineer unless your phone is full of work photos.....

[Graham Mark @grahammark1978]

Anyone know where you can buy spare wheels and spring sets?

[Graham Mark @grahammark1978]

@james_m69 @LBCplumbing To talk, yes, not back to site untill after I've hopefully got some pearls of wisdom.
Thankfully second boiler on site.

[Graham Mark @grahammark1978]

Anyone had an F13 "short circuit cylinder sensor" on a Vaillant system boiler before.
It is a 100kw ecotec but fault codes are fault codes.

NTC's all correct.
No cylinder sensor installed.
New PCB fitted.

Vaillant engineer never seen it.

[Graham Mark @grahammark1978]

@DpawsonGas Harness looks ok, but next step was going to be new NTC all round and harness.

Charging methods have improved so much in recent times.....

[Graham Mark @grahammark1978]

Press is easy Yes, but think about future maintenance, use a compression fitting.

[Graham Mark @grahammark1978]

Ecotec +100kw. 24v switch.
New pcb fitted, ntc's all correct, wiring harness good.
No hw sensor fitted.
Ideas?

[Graham Mark @grahammark1978]

Spot the issue?

[Graham Mark @grahammark1978]

Nope, not touching it, not even looking to hard. Bolts are bent already.
