@needscaffiene since “water stays in reservoir, bottom where pot sits never heats up either” I’d be looking at the heating element for the coffee maker (not the boiler for the espresso) as well as the fuses and thermostat for the coffeemaker. Since it does not heat the water nor heats the warming plate the issue here seems to be a power issue to the heater. You’ll have to try and disassemble the Krups and check things out. It will always help if you can post some pictures of what you find while you do the disassembly. We might get a more concrete idea once we see what things are looking at.
