Hi, I popped the capacitor on and the problem is now resolved. Many thanks to everyone who offered up information. I have quite enjoyed looking at this and all though I would call the installer back for anything more serious I am happy to tinker around the edges as I find this stuff...

Hi The capacitor has arrived form Viessmann and I just wanted to check before fitting, if I could. The wires form the capacitor block just need bending to allow me to fit it into the case - no problems there. On the PCB I to the left of 96 I have wires for earth live neutral all...

Thanks for all the info. As I don't have a capacitor I will ring Viessmann in the morning and order the capacitor. I would think to fit it I just turn the power off and place it in-line between the PCB block (N/1) and the two wires. Thanks

Thanks agile. Does anyone else know for sure if these are the right capacitors? If not then I guess I will have to pay the price and have viessmann take a look...

I see 1 and N on the PCB where 96 is marked and just behind there are two small blue capacitors, does that sound right? Thanks

Sorry it has taken so long to post back I have been a bit caught up. Anyway I did the trouble shooting as described and found think all components are working correctly. However I replaced the Honeywell ST699 controls, like for like, as I noticed some scorch marks on the PCB. Perhaps some...

I will run through the guide but I don't have any issues with water/heating cutting over just the boiler triggering the pump. How would the valve cause that or is this just a good place to start checking? Thanks

Hi, I have a hot water cylinder with 3 way valve also honeywell. I had it replaced about 8 months ago and i can hear it switching between hot water and heating. I have never seen the hot water symbol on the boiler but the water does get heated up fine. Thanks

Ok I take your point on isolating the controls. I would think I have to remove the wire within the boiler or the control casing in effect. I will have a look. On a side note do you know if there are any controls which work well with Viesmann? There site lists a couple but they only...

To be honest I am not sure. I thought the boiler would not fire up if there was no signal as such from a controller. I think because the weather has become a bit warmer I noticed it more so than when it was cold and the installer thought it might just be pump over run. If there an easy...

Hi, First post on this forum so go easy. I have searched the forums for my problem and as I have found nothing I think it must be one of those silly niggles that is unique to me! My boiler is a Vitodens 100-W WB1B regular open vent. My controller is Honeywell, timer box on the wall and...
