Hi all i have a vaillant ecomax 824 2e boiler, however its developed a fault.
When running any tap/shower etc, after 10-15 seconds the water drops in temperature, you can see it drop on the boiler display. On the status its showing up as status 53, which ive read is:
S.53 Appliance is within the waiting period of the operation
block function due to water shortage (VL-RL spread too
big)
I had a friend to have a look at it from BG he recommended i replace the secondary heat exchanger, which he carried out. However after this, the problem still exists? ive tried pressing the bleed valve on top of the pump, theres no air in there.
Has anyone got any ideas what it could be? my mate is calling back tommorow, also he replaced the NTC sensor?
It only happens with the DHW and not the Central heating, ive tried turning the flow down into the boiler and from the boiler but doesnt alter anything
much appreciate any advice
