[doppo189]

Hi have changed microswitch on puma 80.( only getting hw no ch).
Still have same problem, but when i left switch just hanging with wires attached got central heating but of course no hw, fit and adjust microswitch hw but no ch. Which leads me to think problem else where any help please.

Regards Chris

Are you sure you repalced the wires on the new switch correctly, cos it sounds like you may have muddled the wiring!!

Leads me to believe you didn't do the adjustment correctly.

Do you threaten people if they don't push the button?

remember you will not get heating and hot water at the same time with a combi, so, are you saying heating doesn't work when taps are off (but timer and room stat both on)?

Hi guys thanks for replies.

First thing in morning heating fires up, but as soon as hot tap turns on heating goes off. Switch heating to constant heat, boiler fires up for about 2 mins then goes off pilot still alight.

Turn hot tap on with heating on bolier lights up plenty hot water red lcd lights up as should turn hot tap off lcd goes off bolier carrys on working as should but then after 2 mins goes out. Have changed microswitch and set up but no diiference. Boiller potterton puma 80 9 years old

Did you replace the flowswitch, the miroswitch or both?

I thought of that, but how does that combine with:

but when i left switch just hanging with wires attached got central heating

I ususally find that a duff diverter will give some heating, just very little. This sounds more like: sometimes it does, sometimes it doesn't.
