plumbing question.
Discussion
hi all
i have a problem with my heating/water, rads are red hot even when programmer says off, but i have no hot water no matter what my programmer says.
From what others have told me i think my programmer not telling the combi or the diverter valve what to do?
when i turn hot water on, the boiler kicks in and i get hot rads, but no hot water.
when i turn the heating on, the boiler does nothing and i get no heating or hot water
is my programmer faulty or do i have issues with my diverter valve?
i know very little about plumbing, but capable of doing most things myself with a little guidence.
i would get a plumber in, but like an idea beforehand baout whats wrong before he cains me for £500
cheers

It'll be the stepper motor gone in the zone valve. 12.99 from screwfix for a new motor and Bobs your uncle.

not meaning to sound ungrateful in any way, but you 100% certain about this?
is this part of the diverter valve, and is it easy to fit?
thanks again.
Does sound like the diverter valve to me.
Me dad showed me how mine worked, take the cover of the boiler, turn on the heating and see if it moves, normally, it will be in the heating position as standard/off, then turn on the hot water and see if something moves.
Mine had a thing on the top that went up.
It sounds like it is jammed in heating, but, the other response was alot more confident.

They can indeed stick, but that usually happens the first time you switch the rads on after summer...the valve gets jammed with calcium deposits and crud in the system.
If you can move the valve manually, then it's more than likely the motor. It's the cheapest and most likely bit to try first.
You could remove the motor and wire it to a plug to see if it spins, they run off normal 240v mains...don't blame me if you electrocute yourself though.

That's a 3 port. (3 pipes going into the body??)
The only thing you should be able to move is the black lever on the END of the grey box. The other two things are an indicator and the release lever.
Try turning the power off at the wall and see if anything moves on the valve....
Then with the power on select hot water and heating seperately then together and see if anything moves.

I can't open that...LOL!!
I Googled MA1 and it was a three port.
How many pipes are joined to the brass bit under the grey box?
