It’s a super easy replacement, they just have the boiler out to make it easy for you to see. You absolutely don’t need to remove the boiler!
Java_avaJ but there are no instructions about what the tubular object into which the sensor is being fitted.
It depends which boiler the sensor has failed on, steam or brew, but the procedure is the same, just replace the correct one. The existing ones on your machine are probably vrass coloured ones with red or black wires coming from them.
ACS now use a much more expensive stainless steel replacement, as their tests showed that the manufacturers “potting” in brass sensors commonly used in the industry expanded and contracted, eventually breaking the wire, it could take years to do this. You simply:
- disconnect the wire, there is a midpoint connector
- Unscrew the old sensor and screw in the new one with 8-12 turns of PTFE tape (or whatevers required so it doesn’t leak
- Then reconnect the sensor wire
If you are not sure what’s what, remove the lid of your machine and past a photo, then it can be explained for you.
