Swapping a new boiler as old one stopped heating, I checked both fuses and they were ok
Check the elements, there are 2 on the steam boiler, if 1 is open then that stops them. If your boiler comes complete that's fine, if you just get the element part then you must replace all the seals. I replace the seals on a new boiler anyway, originals are silicone and I upgrade to viton seals. Large one at the bottom, 3 small ones on side of base and one finger sized one at top steam pipe. Check switches for operation, sometimes they stick, if CRC does not fix them then replace. Make sure steam tap shuts off properly. The group head seal goes hard over time, replace while you are working on it if it is. Check thermostat has continuity when cold, on the side at the back of the boiler.
The blue power on light does not light up when pressed on my Kitchenaid KES100 espresso machine although the high pressure pump runs when the button is pressed. Neither boiler heats up.
You will need to test for where the power stops & check the fuses on each boiler for continuity. If you find any blown then replace the thermostat on that boiler along with the fuses. The thermostats are different rating for each boiler, don't mix them up. It's highly unusual for both boilers to fail at the same time. Occasionally one of the boiler elements can fail, there are 2 elements on each boiler, check them for continuity. If you have any boiler leaks then replace all the seals on that boiler, the steam one is the one most likely to leak. Buy your own seals using the old ones as samples from someone specialising in O ring supply. There are 5 seals on each boiler. Do not purchase rubber or silicone seals, only use Viton seals, they are high temperature.
