Well, I looked everywhere and I can not find that switch/button anywhere.
I wrote to 1st line but haven't gotten a reply yet its been a week. I'll try to
call them again tomorrow.

Does this mean I'm in need of a new machine?

Is it worth it trying to ship it out
and pay for both shipping costs, and fixing it?

Anyone know if its worth trying to fix an old machine, will the problems continue with something else?


Thank you.
Leoni.

A week's a long time to go without good coffee. Have you unscrewed the big black bottom plate to expose the bottom of the boiler. Your attached photos are of the top of the boiler. Once the plate is off, you'll see the reset assembly. Push the red button. If that's the problem, it should spring right back to life. I've had to do that several times. And yes, the machine is definitely worth  fixing. Not too much else to go wrong, in my experience.
Hope this helps.

There is a chance your machine doesn't have the safety thermostat. I have a BZ99 which uses many of the same components and the same boiler, and only certain releases of it had the safety thermostat. Indeed a wiring diagram I have refers to the "con termostato" ("with thermostat") version.

If you have it, it will be exactly where SP mentioned. I agree it is definitely worth fixing. If you haven't got the safety thermostat, your heater element may likely be blown and they only cost about $90 to replace.

If you have a multimeter and are confident enough not to forget to unplug the machine from the mains, you can easily check if your heating element is blown. Indicate if so and I or someone will lead you through it.

THANK YOU , THANK YOU , THANK YOU SO MUCH. Everyone of you.
I should have remembered about unscrewing the bottom plate.
I did that yesterday, and found the switch/red button.  Reset it,
and the heater is working.

Thank you all. I have my machine back. Whewww!, I was already thinking
I had to buy a new one. That would have sucked, I had just finished buying
3 o rings/rubber rings, and 3 shower screens.


I'm grateful for this site, I know I don't show up too often, but its too addictive
for someone like me who loves gadgets.

Thank you again.

Leoni.

Wondering if you guys know how to reset a thermal switch that does not have a reset button? My Bezzera Bz99 is from 2001 and mine has no rest button :(

Without a button, it's supposed to be either a disposable or a self resetting.  When it gets cooled back down to less than boiling, it should reset if its a self-resetting.  If it has stopped resetting (Or wasn't a self-resetting), it needs to be replaced.  You could try banging it on the table. If you're throwing it away anyway and you think it's supposed to be resettable, you're not making it worse.
If you're replacing it, get the one that you can physically reset with a button.
