Hi All,
First time post here so please go easy on me
I have an old BES820 machine and the issue is that it heats up fine when first powered on, makes all the right noises. however it will not hold heat. first extraction is ok, but then water will rapidly cool after that.
Can still pull single or double shot but they're luke warm then cold after a while.
I have checked the thermistor and it seems ok, like said it comes up to temp, then can hear relay click and that is it. Wont come up to heat again after that, could it be a faulty/sticky omron relay? Also the Thermoblock still has 230V to it at this point, so could it be the Heating element?
I also cannot find a schematic for this machine online, anyone have access to this?
Any help with this would be amazing, would hate to have to throw it in the bin.
Thanks in Advance!
