Eco-max 824/2e

Hi,

Boiler has heating but hot water goes tepid then cold and there is no tap icon on the display. New diverter fitted but no change. No fault codes showing. Could it be the aqua sensor or the dhw ntc.
Many Thanks

Peter

 

Hi Peter,

The Ecomax series has the ability to both enter diagnosis mode or test mode to try and find a problem.  This is usually reserved by competent and qualified service engineers with the Service and Installation Manual.
