My expresso machine won't steam. Just suddenly stopped. Have tried running vinegar through system, but still won't run through steamer.
Hi, I dont know which brand machine you have, but I should be able to work out what is wrong. If your machine has a press button or turn knob steam tap, then it could be the solenoid which opens the steam flow. The solenoid itself maybe stuck or the coil maybe faulty. You just need to work back from the steam arm to work out which solenoid it is. It should make a clicking sound when activated. Commercial machine solenoids canbe disassembled and cleaned. If its a domestic machine, then just replace the solenoid. Also, some machines have a micro switch that activates the steam valve. If its faulty, then replace it.
If its a domestic machine you have, then another thing that maybe at fault, and that is the thermoblock (small boiler). If it doesn't heat up then no steam canbe made. The thermoblock has an element inside, and they can not be replaced. You have to replace the whole thermoblock. It can be easily checked with a multi meter to see if the circuit is broken. On some thermoblocks, is a thermostat or overload sensor. It is also easily checked with a meter.
So lets break it down a) solenid
b) micro switch
d) thermostat/ thermol overload
Hope this has help you. Id be looking towards the thermoblock. Dazza
