diverter valve

So I've just had a visit from a HomeServe Vaillant/Glowworm engineer to fix my boiler. The water was cycling hot and cold every 4 or 5 seconds. He was reluctant to attend saying the problem was most certainly blocked plate heat exchanger and said I should get a power flush first. In the end...

Hello, I have a Worcester Greenstar 35CDi combi boiler, installed in early 2006. Generally I have had no problems with it. However on three separate occasions - at roughly equal intervals, most recently yesterday - I've been away and come back to find that the HW doesn't work. And after a day or...

Rads getting warm when CH system is off vaillant eco tec. Brief vid on how to change DV Valve https://www.youtube.com/watch?v=_F7AZHepZM0

Hi A problem has recently started on my Main Combi 30 Eco elite. When the CH is set to off on the timer the upstairs radiators are getting hot. This seems to get worse when the hot water is running for a while. I have noticed that even when the CH is off and no hot water is being used the...

I am trying to troubleshoot a diverter valve that seems to be stuck, so I can only get water via the shower hose. I cannot get water through the bath taps. It is operated by moving a ring or collar. I have another one which works correctly and I think that I can hear a spring or something inside...

My boiler is 11 years old (the system was power flushed then). Just recently the hot water started to cut out. I contacted Vaillant who offered a £300 fixed repair contract. I have had two visits. On the second visit the diverter valve and plate heat exchanger were replaced. The first visit the...

Hi, I have a fault on my boiler which is causing the Divert valve to continuously motor open/close with consequential impact on the CH and cycling hot/cold water when DHW demanded. I have found 240v is permanently on the CLOSE terminal on the divert valve, when CH is demanded 240v is applied...

Really hope someone can help me in any capacity please.i have an iqe combi boiler.central heating is working fine but the problem is i cant get the hot water to come on.the temperatures on the boiler itself are correct aswell as the pressure. Also the hot water symbol on the boiler display...

Hi, Can someone advise me on how I remove my shower diverter pictured below? I need to try and fix it as it has stopped diverting water between the shower and bath which I think may be due to limescale as we have had this issue elsewhere. I can't work out how to remove it though, there is no...

New diverter valve and now radiators are warming up during hot water mode. It never used to do this with the old valve. Had to have a new diverter valve fitted (brass type) as the old was leaking. Now whenever I have a shower, I notice that the rads are getting hot. Not good for this kind of...

Hi Had my boiler virtually rebuilt about a year ago by BG - new heat exchanger, diverted valve, pump. Have an issue starts this morning in that the heating won't turn off. Hot water works really well, no loss of water temp, programmer (electronic, built into boiler fascia) set to off for...

Hi, 1st poster. I have a Atmos HE 32 combi and get intermittent hot water on the DHW side. The boiler and system are 10 years old, CH system flushed on installation, and 5 years ago as well as inhibited afterwards. The unit is connected via a Solar HW store and the problem has existed for a...

Dear all, I have just moved into a new (old) flat, with a pretty absent landlord. He did show me around the flat, but I get the impression he takes the 'patch it up' approach to repairs and he and the previous tenants have tolerated various glitches in the heating/hot water systems over the...

Hi I have 2 problems, I've replaced the gland nut on the front of the DHW diverter valve, some 8 months ago, but it is now leaking again from the pin directly behind the micro switch, mainly when no heating has been on. In addition as the hot water takes a while to heat up, I have to put the...

Hi. Just moved into a new cottage. Boiler fires up great and has the radiators and hot water pretty hot and quickly. I've realised though, that the controls don't seem to be working. 1) There is a room thermostat, which does click on and off but doesnt seem to affect the boiler in any way. I...
