Hi,
My Vaillant 20/1 T3 was turned off for the best part of a year, when tuning back on I noticed a small leak on the Expansion vessel, but the boiler fires up fine for Heating & Hot Water, However, when turning up or down (settings 1 -
the 'Flow Switch (mounted on the front, inside cover), does not always respond correctly, if I 'tap' around the switch, this will sometimes appear to make the switch respond...any ideas what is not working correctly....can it be easily fixed. Also where is a competitively priced place to purchase a replacement Expansion Vessel?
Lastly I would like to get the boiler serviced and obtain a service certificate (LPG Gas Safety) can you suggest someone who operates in the Rochester Kent area.
Any Help much appreciated.
