Below are examples of faults people have experienced with their Vaillant Aquaplus boiler.

I am having some problems with my vaillant aquaplus vui 362-7 combi boiler, When hw tap is continusously opened the dhw temp exceeds the set temp by the dial by long way

It appears there is a problem with DHW upper limit setting, perhaps the PCB does not see it

The above lead me to examins the d codes, and discovered the d50 shows 113 oC

Can any one help to resolve this ?

We have a Vaillant aquaPLUS in the family (mother in law) that intermittently plays up.

Bit embarrassing because whenever we go round it works perfectly, so it is really difficult to diagnose.

Problem is that when running HW it sometimes goes cold for a while. Apparently the tap symbol remains lit. The heat exchanger is clean.

We have changed the diverter valve this week, and mother in law said it was better. Next day she rings to tell me it is back to its old tricks.

I don’t want to change a load of parts unnecessarily; Vaillant have advised changing the NTC but in my experience these are not intermittent, the resistance is either within limits or it isn’t.

I was wondering whether other Vaillant experienced types Eg: dangermouse or Dave had any suggestions. Did wonder about the fan switch but no error code is logged.

Any ideas?
