[plummerman]

Dont trust the pressure gauge saying zero if it's stuck. I'm sporting a beautiful bruise on me chest for bein cocky with one. Cracked it open with bucket to catch the what I thought would be the dregs an bosh. Shaking, wet and slightly bemused engineer

Wha he said. It will be plastic diverter cartridge ideal part number 174200. 10 min job to change

You must be a very quick worker!

The last one I changed was on a Biasi Aquapiu although the same part.

Whilst it would rotate, with difficulty, it would not pull out. I had to resort to carefully breaking it up in situ whilst preventing the bits droping inside the boiler.

Took me most of 30 min!

Shut off isolating valves put hose on drain valve and as it's draining remove pcb and valve head unscrew using key, screw new one back in and put boiler back together then refill.
Great wee job to do

Ive just done this job and now its stuck on "D".... The water is red hot but the central heating isn't warming up?????

When you turn the boiler off and back on you can see the motor operating the valve and "c" is displayed for a split second then it moves back to "D"?

bled the radiators and still nothing?

HELP!

 

[engineerman]

have you put the valve on the correct way round?

I didn't realise i could get it on wrong? could i have put it in upside down?

I have now turned off the cold water in and its now working as it should but now stays on "C" when the controller is turned off. I turned the thermostat off (even thought the it should be off anyway) and it went to "0" as it should for a minute then went back to demand????

Could it be the timer?
