Thanks, at least I now know the source of the problem (I hope), but when I rang Halstead technicians yesterday, I was asked to change the inner service kit of the diverter valve as well, as the technician suggested the leak could also be occurring from there! All I wanted to know is whether I...

OK I have obviously not done it correctly then, as the new o-ring was simply placed round the spindle of the diaphragm disk close to the point where the spindle passes through the front end seal. In other words, it would be moving with the spindle inside the housing. I can’t recall if I...

I believe I must have but I can’t remember (sorry) as I did this a couple of weeks ago, and have been noticing the source of the leak ever since. As I undid the old nut from the housing, surely the old ring would have come out? I tried to press the new o-ring in the small recess inside the...

Replaced the diaphragm in the diverter valve DHW flowswitch due to problems with hot water. The old diaphragm was cracked, and the boiler now works fine under both hot water and central heating, except for very slight water leak which persists from where the flowswitch connects with the main...

Did you have any repairs done recently? I had a similar problem with my Volvo S40 but eventually spotted the leak to the absence of seal to the rear light that was letting rain water in after I noticed that the spare wheel housing was filling up with water. I took it back to the garage where...

A Halstead Wickes Combi 102 (Ace High) installed in a let property fails to modulate to full heat under demand for central heating, so the radiators are not getting hot. The pressure remains stable at 1,5 bar. When hot water is called for, the boiler responds to full heat. After a while the...

I had a similar problem on my Halstead Wickes Combi, and (thanks to this forum) took the trouble of cleaning the DHW exchanger (with citric acid), drained and later flushed the entire system with Fernox Restorer and thankfully its all working fine. Need to add the inhibitor though, after...

I have a Bosch Washing Machine WFF1201 which is now over 5 years old. After starting it seems to get stuck on the water fill in cycle and does not seem to wash. Manual turning allows spin, but wash cycle does not complete automatically. I have cleaned the dispenser tray, and noticed that...
