Hi there,
I have Vaillant ecoTEC plus 837 for over 4 years now never had any issues. yesterday I turned itself off, I was worried checked the fuse and changed it then a little tap on the front panel turned it on again. since then it happened twice and little tap turns it on again and working fine after that.
Any suggestions? worried don't want big repair bill.
thank you
