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

do not take it personal , leave Vaillant to take care of it as it has nothing to DO with you !

hope customer is a sensible person and understand this .

should have install WB mate 🙂 just kidding 🙂
 
The saga continues,have been back today for 4 hours boiler on full burn 22 mbar at the meter 18 mbar at the boiler mi s say 16mbar ,all appliances on ie fire ,hob boiler 19 mbar at the meter 14.5 mbar at the boiler ,I fitted a test tee before the boiler isolation valve retested all app on 18 mbar .I phoned gas transporter they came out and changed governor to take this out of the equation as seal was broke ,checked pipe run 2.3 m of 22 mm and 1.6 m of 15 mm pipe retested after guv changed same results,the thing is the fault appears when the boiler is running on it's own ,waiting to hear from eng ,after leaving 2 hrs later f61!
 
losing 3.5mb through the appliance doesnt sound likely? Are you sure the test conditions were the same?
 
Yes test conditions exactly the same,I specifically mentioned this to eng,but seemed to focus on the guv.now this has been changed I am waiting to hear to what he has to say on this point
 
Valiant have spoke to customer and are going to change boiler! However have not received a phone call explaining fault I am still curious ,post your own diagnoses
 
Hopefully I ve got 3 to install next 2 weeks ,with all the call outs and testing we must of burnt £50 worth of gas! We ll see what the service side will come up with in regards to looking after the customer
 
Fitted the new 28 pro last week. Customer rang to say F.61 showing on display. I told her to press the reset. I hope its a one off
 
had a problem with new boilers locking out and both different makes. each time it was the co2 setting was slightly down and due to the clever boilers nowadays if the setting is anything but perfect they lockout til custard resets. Each time after much hair pulling, reset co2 to mfis and off they go happy as sandboys.
 
Uh oh this is starting to sound a bit worrying especially since even Vaillants own engineer's haven't got to the bottom of the fault! The company I work for only fit vaillant and so far we haven't had any problems with the new ones but its early days! Wonder if f61 will become the new f75
