Thanks for this thread. I had a problem with a Bezzera 99S machine and with the help of this page, traced it to the transformer. I substituted a 15 volt output version to check and after a couple of cups of excellent coffee again, I tracked down an exact replacement from RS components. RS Stock No. 732-0354 Mfr. Part No. VB 1,5/1/18
Thanks to all!

The transformers should be a standard pin spacing.

Try searches for

Vigortronix PCB Transformer

Block PCB Transformer

Myrra PCB Transformer

Supplier in the UK include Farnell and Rapid Electronics.

Always check the rating and pin layout.

I'm stuck with a similar problem! BZ99. GICAR RL40/4ESS/F. Pump won't shut off on boiler fill cycle when machine is cold. When able to heat up GICAR it worked normally for a while. Now it just overfills and runs water out of the popoff valve. I got "an original RL40/4ESS/F from England, but it won't initiate fill! ANybody got any advice? Other than trashing machine, that is. This guy is my buddy, and has been for years.

Another common mistake we can make is sharing what we have written with our wives! As hobbyists, it's good to get feedback from everyone - even the missus!

Lol!! Sounds like my room. My sister came in a week or so ago and said, "Dang, there's not even enough room to walk around in here!!".
That's just the way I like it.

Hey Bernard,
Unfortunately my friend took his coffee machine back and so I am slowly coming down off my caffeine high. Hopefully someone else's machine will break down and give me a chance to 'repair it' (and test it thoroughly!)
