I have posted previously about our boiler issues.
None being gas related.

After much messing about, our boiler issue was with the diverter valve.
This has now been replaced with a new one, but I still have a issue.

The problem is with the DHW only.

When a hot tap is turned on, the boiler fires and we get hot water. After about 10-15 seconds, the boiler stops and turns off for about 5 secs and then re-ignites. This happens ALL the time.

This issue was not present before the diverter valve was changed.

Hoping someone can point me in the right direction.

Thanks for reading.

How soon after the Diverter was changed did this problem arise ? If it wasn't immediately ,it may be a blocked plate heat exchanger.

Hi, I’ve removed and flushed out the heat exchanger, but the problem persists...
What for the next move.

The issue was apparent almost straight away.
Thanks

Call 'em back?

Hi, I changed the diverter.

I have just removed the connector from the temp sensor and the dhw is still having the same issues, would this indicate a sensor failure ?


Thanks
