Hi, Thanks for advice Picasso, got new stat, changed, worked for 2 days, then same thing. Googled my programmer st9400c, turns out that when led is on it doesn't send enough voltage to boiler. Switched off led, working now, hopefully will stay like that. Tomorrow will write email to Honeywell...

Hi all, Just like from title for the last 2 nights our water didn't get heated. So today I manually on a programmer switched water - nothing. Programmer light went on, but boiler and pump didn't kick in. Tried same thing 10 minutes later - everything worked. So obviously something isn't...

Hi, So I tried to use shaver adapter as a US to UK adapter to power my notebook. It was working fine for some time, and then it stopped. Yep, fuse got blown... Anyway, would replacing 1A fuse with higher rated fuse would be safe and feasible? Thanks, Jay

Hi all, So since my last post I have replaced 3 port actuator AND put new Honeywell programmer. Called electrician who tested everything and everywhere and he couldn't find any faults whatsoever. It still happening, boiler completely disregarding thermostat and programmer. When electrician...

Checked with another 3 way valve + actuator but still having same problem. Basically when everything switched to OFF on programmer boiler still kicks in. It doesn't stay on constantly, it will work and then stop again. So something tells boiler to switch on, but what? Any ideas anyone...

Hi everyone, This forum helped me a lot in the past, so that's why I think you will be able to help me again. I can not understand what's going on with my boiler. It's switching itself on for no reason at all. My water is set up to heat at night time for one hour, so by seven...

Ah, my bad, I misread what you wrote earlier. I'm going to give it a go on my days off. Cheers!

I would try it, but like I said earlier i can't undo valve, worried that I could break tap or crack sink :(

Hi all, I've noticed that water was dripping from under my tap. On closer inspection I realized that it was in fact hot water tap which was causing this problem. It's a mixer tap, and as you can see on the pictures, it's leaking from under the circlip. I've tried unscrewing whole hw valve...

Right guys, I just had a blonde moment, but long story short- it works, done it the way D_Hailsham advised. Thank you guys!!! BTW is it me or thermostat shows higher temperature than it really is? I have room thermometer and it's readings are 3-4 degres lower....
