Valliant have been out today ,according to customer they have changed " a valve" and also found a dodgy connection ,I am doing some other work there tomorrow so I ll find out exactly what they ve done,they ve not left report on work carried out ,and did not ring me to ,customer says they wrapped part up to send back for test,I'll keep you posted

 

[Leo21]

That's the end of it then, your customer won't know and vaillant won't tell you. If anyone here hears about this, can they post it so we can see if there's a trend.

According to the manual F61 is a "Gas Valve Control Defective" -"Short circuit/earth (ground) leak in cable harness to gas valves, gasvalve assembly defective (earth/ground leak from coils), electronic control system defective" so in short (pardon the pun), an electrical wiring fault (short) or electronic failure.
I've never had any have this fault before but Ill be sure to look out for it.

Don't you just love that, the mi,s give you a dozen things to look for. And then you have to face the customer with a blank face!

Vaillant eng report,bad connection on the nuetral of the gas valve ,gas valve changed.had no more problems since.eng did not have gas valve on van which I summise this is not a common fault ,looks like a one off .i must say I ve had very few problems with Eco tec range

 

[lolipop]

F61 showed up again,it's gone about 10 days,eng has changed wiring harness and venturi this time

 

[hydrotherm]

Thanks for the update. Please keep us posted if the problem has been solved.

Sounds like a nightmare. Hope it gets sorted soon, as I cant imagine your customer is best pleased with all this from a brnad new boiler.

I ve just spoke to customer he s been quite patient about the situation,vaillant have been back out and changed pcb ,it sounds like there are 2 boards one for ignition one for display waiting to speak to eng to get full report

How are you getting in touch with the engineer. On the odd accession I've called them out I get a vague report of the customer. Is this a service they offer or do you know the engineer?

 

[SafeGasInstall]

Omg what a drama ...

. Did you select the boiler for your customer or it was there choice

Vaillant customer service ask you if tou want eng to give you ring ,however they hav nt today but the sales rep rang me ,they ve changed pcb s and gas valve again,also mentioned low gas pressure when all appliances are on.the thing is this fault keeps appearing when only the boiler is on .I had 19 mbar the previous eng had the same as quoted on reports .mi s say minimum of 17 mbar

I recommend valiant boilers on every job I quote for never had any problems like this before ,I know the customer but I am starting to get funny looks of him now

Every time vaillant bring out a we model theres usually problems! But they sort it. Where abouts in the world are you? My reps challenging to say the least.
