Mend Baxi 105e Boiler Noise Valve

Baxi 105e clunking noise every time I turn a hot water tap off?

Baxi 105e 4 years old. Whilst the boiler seems to operate properly, every time you turn off a hot tap in the house, the DHW valve appears to snap shut very noisily which transmits through the pipes.

When you watch it operate, the valve spindle is obviously free and the second the micro-switch operates, it quickly shuts with a clunk.

If it's normal - fine, but I would have thought it should shut more quietly.
Could it be something to do with the diaphragm/spring perhaps?

Thanks Kash. It happens when any of the hot taps are shut off so it's a common problem to the boiler. It's not that bad but if it starts to niggle me - I'll get the diverter valve repair kit.

Cheers

hi its just when a valve gets worn u hear water hammering noise does it happen on all taps and if so u will need a diverter valve service kit to repair if it happen just on the one tape then it the tap thats worn. but in any case it nothing to worry about either live with or get it repaired hope this helped
