Vaillant VCW GB 242 EH hot water goes cold?
When i turn the hot water tap on in the bathroom or in the bath, or the kitchen the water comes out very cold then very very hot, then very very cold the hot water just seems to be knock off all the time.
If using the mixer tap in the bath the hot water comes out very hot then when u put a small amount of cold water it just goes completely cold.
PLEASE HELP
