Vokera sabre 29he got water fault

[Piperdave22]

hello!
Has anyone worked on these Vokera sabre 29he combi boilers? I have one that when you run the hot tap it clicks loudly at pcb area and goes cold then hot .

Initial thoughts are a blocked heatplate but it looks like I have to take everything apart just to take it off and check it!
Has anyone taken one of these of and know how long it will take? And whether the boiler has to be dismantled?
Also suspecting divertor valve or water turbine can anyone point me in the right direction?

Central heating is working fine with no probs

Hello and welcome,

Not me personally but one of the other lads will surely help you out.

@king of pipes, @Harvest Fields, @ShaunCorbs,

Morning. Think some of us did mention about them being gas safe and waiting for the badge and post to be moved.

This is now in the gas safe section? Do you have any ideas at all @Harvest Fields ?

This is the gsr section

No need to be like that mate . You have not got the GSR BADGE. Easy mistake to make.

Have not had this problem before mate. But will have a look at my bible when I get in. Leave it with me.

At home now mate. How old is the boiler?

 

[Harvest Fields]

Is it definitely not doing it on heating as well? Just because the rads get hot I would not take that as a sign it is not doing it?

Plates are susceptible to blockages on a dirty system.
You can remove them without removing owt else although fiddly and also I'd be tempted to change the thermistor at the same time. Easy way to check is run hot water and at the time it shuts down, turn the cold supply lever off underneath and if the temp shoots up to the 90deg limit, then likely to be blocked plate.
