CON error on vailiant eco tec plus

[mutley racers]

The pressure gauge says it 1.5 bar but the digital dial says 0 bar. So boiler is not firing up at all. Is this a new board guys

 

[solutions]

I would be tempted to get a seperate pressure reading off a rad plug or something with your own known working gauge before drawing conclusions from the boilers conflicting info. Bleeding a rad alone will give you a brief indication as to whether there is any real pressure there. Could be the pressure sensor itself (the one supplying the board with the info for the digital read out).

 

[mutley racers]

Definitely got pressure in the rad as I did the bleed test to make sure

It should be covered under the warrenty mate shouldn't it?

Am not sure when it was fitted. Over 4yrs though

Blocked pressure gauge , did you pres the " - " bottom ?

 

[Chalked]

Most likely is the pressure sensor. They seem to get blocked and can't be cleaned. They are then fixed at a certain pressure and then the pump proving does not sense a pressure increase.

The The pressure gauge needle moves up and down when draining. Just doesn't show any pressure on digital screen. Only 0. Is that the minus button?

 

[SafeGasInstall]

Yes mate the minus

 

[mutley racers]

Yes mate the minus

I did. Nothing happened

 

[SafeGasInstall]

Then this will be a problem with te Presure sensor as mention above ,did you ring manufacture ?

 

[mutley racers]

No didn't ring them. Typed code in net and people said it usually means pcb has gone

 

[SafeGasInstall]

i will say ring them tomorrow morning just to be 100 % sure

 

[mutley racers]

No didn't ring them. Typed code in net and people said it usually means pcb has gone

Will do, thanks feller. And all other guys who replied

I work on Eco tec pro's a lot always been the pcb when con displayed replaced one today. Never noticed the pressure difference between gauge and digital before.

But was it flashing CON constantly? Mine was only every so often. And when I turn the tap on it shows the digi reading as 0.0 bar

 

[breakdown]

Never seen that fault before. Will ask the lads tomorrow and re post if I find out anything.

CON is PCB. Can throw up some strange faults, seen the temperature at 0 and strange goings on.

So, are you saying you believe the pcb needs needs replacing? It's an expensive part to buy if not

 

[mutley racers]

It was the pcb guys. Thanks all. Get yourself a drink in the arms from me
