I have turned up the dhw thermostat on cyl ,and the boiler runs on hot water ok However,the CH 2 port valve does send a signal to boiler to come on(then dies out almost straight away as above)

As per title,my boiler goes throught the ignition sequence,fan comes on,burner ignites then 2-3 seconds later burner goes off and boiler goes into pump over run. Been fine for 4 yrs no problems. System on fitment was all new,with Vaillant unvented cyl Any ideas please? Thankyou

So hertsdrainage what is the cure funny man? She had boiler changed 18 months ago,no other work since.

I can't see where the pipes enter the loft so I'm unable to trace it back. They built the pipes into an inaccessible area for some reason. The expansion tank also has one going over the top,but I guess it could be they are the wrong way round. I did plug the exp vent when changing the zone...

Its the cold tank,overflowing because the vent is filling it Thanks again

If the expansion tank is lower than the main tank it cannot leak into the main tank as it has less gravity pressure,it would fill the expansion tank up,not the other way round. Thanks

It runs into the tank even when ch pump is not circulating.Expansion tank is lower than main cold tank and no signs of expansion tank ballvale operating. Unfortunately the mains stopcock does not fully close the water supply off and has been fitted behind a kitchen unit where it's very...

I take it the boiler is actually igniting when the hot water is run and not just making a noise? If it is igniting..with the heating cold,run a hot tap and see if the heating flow pipe becomes warm. It should read diverter valve(stupid auto correct)

I have a problem with someone's cottage. Gravity hot water and upstairs cold. Oil boiler,room stat,cyl stat 2x 2 port with auto bypass. The customer noticed the overflow dripping,so I went into the loft and looked into the tank. Ball valve shut but water flowing up the hot water vent. The...

Diverted valve stuck on heating

Hello,I need to change a wilo gold 50v pump on a system boiler. Question is,can I just fit the head off a standard pump or do I need to fit the correct part number one from the Ariston parts list? It's for a Microsystem 21. Also,is a grundfos pump head a direct replacement for a head...

Hello, Does anyone have knowledge of these boilers? A friend has frozen condensate but it appears to go UP from the boiler...is it pumped? Ive not seen it,he just tried to explain it over the phone. Thanks

Not had the top off,but sounds like pump turning slowly Best description i can think of is it sounds a bit like a washing machine when it spins slowly just after fill up Did not realize you could change the pcb,not had trouble with one before except under warranty

I have checked the filters and it is an old one,late 03

Went to look at a Aqualisa Quartz (pumped)shower today. When power is on (but control button off) It makes a noise like the pump is turning slowly and sounds like air is in the unit. If you turn it on at the control it works fine and sounds normal. But when you turn it back off it makes...
