- Both the wires are attached to the same terminal. and there is the equivalent on the other side aswell.
- I will look into getting the PTFE tube and .
- Not tried to remove the cartridge. Looking at the parts catalogue it appears that they are inserted and held in place via screws at the front and back of the brew assembly. Not entirely sure how the cartridges can be checked for failure.
History of the machine is:
Bought August 2019 from a coffee roasters, who probably had it for a while. They say they only used tesch ashbeck water.
It was serviced in July by ESTech as per the recommendation of La Marzocco
- I guessed that might be the case. Probably just taping them up properly…will be fine as a short term fix.
- That should sort the drainage
- If it were me doing the heater cartridge, I would do it 2 possible ways, either with heat sink compound (non drying), or with a press fit. The screw would simply be to keep them in place/ensure their are in far enough
The problem with heat sink compound, is it invariably dries, you might be able to use a liquid metal compound, buit there is always corrosive reaction worries, as I assume the head block is made from Aluminium with a steel wet liner (that’s how I would probably do it with that design) The better way is to press them into an extremely well-designed brass holder that is a press fit into the group, or similar. I had a look at a photo and I think they are put in with heat sink compound.
Either way, removal will probably be a destructive process for the heater and I still have no got to the bottom of why you want to replace it. I will ask again, do you think a heater has failed. To test the heater, you can simply use a meter set to the resistance scale and see how many ohms it reads. If it’s burnt out, it will be open circuit…if it’a a direct short, it will have either tripped a fuse inside the machine or your electrics. There may have been some problem, because how did that limit stat button get broken?
The history doesn’t state the date of manufacture, which will be on the rating plate of the machine….it’s handy to know how old it is, as that guides maintenance and fault-finding.
Until I see some larger pulled back shots, I can tell nothing else.
