Thread: ECM Giotto - No Steam Pressure (low boiler temp?)

So, with much sadness, my ECM Giotto has developed a fault, hoping I can fix it myself if anybody has advice or troubleshooting tips.

Turned it on and found there's no steam pressure. That is, neither steam or hot water come out when their respective taps are opened.
The boiler has water in it, boiler filling pump works fine (cleaned the sensor just in case), and the brew pump works fine to pull water through the group head.

The machine gets hot, but just not hot enough to create the required pressure.
Discovered the boiler only heats to ~78deg C. I tested this by opening the machine up when left on for an hour, and probing into the boiler via removing the vent in the top.
Also the group head is not as hot as usual.

Thinking it may be a partially faulty heating element, as when I turn the machine on it's much quieter heating the water than normal (practically silent, vs more of a kettle heating sound as it used to). Or perhaps a bad relay not functioning properly when warm?


Any ideas on how to resolve, or troubleshoot? Aside from taking it to a technician (the last resort)?
