I have two issues with my Vaillant VCW NL 282 E that I am hoping you guys might be able to point me in the right direction on. The last service on the unit was some 8 months ago and I want to avoid the extortion I usually receive when calling boiler engineers here in Holland.
My problems started about 5 months ago, heating was working fine but hot water was tempremental, the shower would be fine for hot water (although not exactly quickly or reliable) but other hot taps in the house would not provide any hot water unless the shower had been run first, then a short amount of hot water would be available.
Unfortunately I left this issue alone and just suffered. I then left the heating off for a few months. During this time the hot water stopped working completely and I realised that the servo that engages the microswitch was not doing its job. If I manually press the microswitch the boiler fires up, if I hold it in position hot water is maintained perfectly and when I turn the hot tap off the servo appears to fight to push the lever away from the microswitch (making a clicking sound) before I manually push it back in place and all is well.
Then about a week ago I turned the thermostat on again and found that the heating is no longer pumping, there is no hot water entering the system at all and the boiler doesnt fire up either.
I've read a lot of posts on here about diverter valves and servo's but as I have a combination of the issues those posters reported I thought I'd get some advise.
Many thanks in advance for any tips ! (photo's available on request, of the boiler )
