Valliant turbomax boiler dilemmas

[Ruksa a]

So we moved into our home about a year ago and i am seriously getting uptight with the boiler

We had it serviced last october and then the problems started and still not resolved

started with error message f64 - called our home insurance people who sent out a engineer who literally pressed the ‘restart’ button a day before christmas eve

so thats what i have been doing - everytine we get f64 error message we restart the boiler ( noticed it usually happened when we had both the heating and the hot water on

or if i was having shower and hubby using the hot tap downstairs in kitchen

today i noticed the pressure has gone below 1 - so adjust the pressure right !
Looked below the boiler and nothing to turn just two bolt like piping sticking out

i dont know what to do? Where can i get a key to turn during lockdown and what about the error message f64 - could it be linked to the low pressure

seriously getting stressed out - should i call my home insurance as feel the engineer they sent was rubbish and hasnt resolved the original issue !

The pipes sticking out should have caps on them, and you should have a flexible hose to connect. Remove the caps connect the flexible hose and open up one valve or 2. If you can post a photo it'll be better to explain. I suspect your F64 code is similar to that of other Vaillant's, in which case your home insurance person hasn't done the job correctly. Sorry I can't tell you what it is, as it's against forum rules and possible have-a-go types. So yes, I'd be contacting the home insurance company.

Hi

now looking at it there is a slot in the middle which suggests that they can be turned ( maybe with a screwdriver)

still unsure i should get home insurance out to fix the original issue especially whether they can attend on easter sunday

Hi and thanks for the photos, however the only one of any use is the pressure gauge one. You’re looking for something that resembles one of these:

External filling loop:

There may be an internal filing loop, but not sure on that boiler what it looks like. The home insurance company can wait (at least a couple of days) as long as you can reset your boiler and can re-pressurise. The F64 is likely to be a part, so may not have it anyway, and depends if parts are included in your premium? If not engage in a gas safe registered engineer, preferably a Vaillant specific one.
