Baxi 105HE Central Heating issue

[DIY_Guy]

Recently I've noticed that the radiators are getting warm despite the dial on HW only

It seems when the tap is turned on for HW it also for some reason turns the CH on

Any ideas what could be causing this please

Thanks in advance

Diverter valve passing

Agreed your Divertor valve is letting By you have two options , replace complete valve or fit service kit , depends on how confident you are .

Changed the diaphragm not long ago too as the water kept getting cold mid shower for a few minutes and would then get warm again.

What does the service kit comprise of?

Bits to service the valve

I never bother replacing the guts,just change the whole divertor valve.some guys do buy the kit and "service" the valve..take your pick.

Just strip it and clean it no need for the valve or the kit , its merely a bit of gunge on the pin clean and grease it lost count of how many i have done

Each to there own..cant believe you never get called back to a polished up one ever..and you gonna tell me its a 5 minute job...so you guarentee the repair....what a prat one..just replace it

half hour job to strip and clean so customer is only paying for labour and first time fix as opposed to an additional 100 quid for a valve . Never been called back to any it is caused purely by restricted movement on the pin due to build up of gunk nothing else ,

Lookin at that pic..there is not much inside them.never took much notice or fancied strippin one down before.did one the other day.couldnt believe price of it.will strip it down in future.thanks for tip.every day is a school day..esp in bleedin plumbin!

You cant buy the baxi official part of the service kit as far as i know so new valve everytime for me

 

[gas112]

the boiler was not a baxi to start with it was an alpha that baxi bought the rights to hence why the service kits are alpha . bUT HEY IF YOUR NOT CLEVER ENOUGH TO WORK OUT HOW TO FIX A BASIC FAULT GO FOR THE EXPENSIVE PART THAT Is not required. fek i am nt changing all those upper case
