Hi everyone,

I think I have a problem with my reset button on my Bezzera BZ02 .
My gage was not moving again, and I went to open the bottom panel
so I can get to the red reset button, but it didn't "click" just kept pushing
and it didn't engage.

Do these things need replacing from time to time?

Thank you.
Leoni.

It sounds like the reset is defective but, to answer the question more directly, no they do not, for the most part, wear out and need replacement. In fact, they should not ever trip at all if all is well with the machine, it is there for safety, to prevent a bad event on a large scale.

Rarely need a replacement safety. You need to check the safety and heating element with a multimeter for continuity and resistance.

If you have reset the safety in the past, this means your machine was overheating. One culprit is limescale on the pressurstat - making its diaphragm stick to overheating.

We would suggest you check your water - if too pure, the machine will not heat.

Finally, it could be a bad brain unit (black box).

Caldblack, Jim,

Thank you for the replies, I appreciate it very much.
Yesterday for some reason the reset button re-set correctly.

Jim, I am using spring water, and have been since I bought the
machine, (from you guys ;-) )  
In the last month or so I've had to reset it 3 times.

Where do I check for limescale on the preshurstat?
Also...
How do I check the safety and heating element with a multimeter? Do you sell them?

Thank you I appreciate the help. I would hate to think my machine is dieing on me so soon.

Leoni.

For legal reasons, I can not offer electrical assistance in a public forum. A multimeter can be purchased at your local Sears, Home Depot or Lowes, etc. The digital ones are more expensive, but much easier for the newbie to use and learn. It is best to get a friend or neighbor to show you how to use it. There are many places you can learn online.

You need to confirm first if the unit is overheating. Do you have water on the counter or on the bottom of the frame? In other words, you need to pinpoint the trigger that is causing the effect.

Thank you.

I will go and buy a multimeter tomorrow.
The water is in the tank. I don't know exactly what you mean pinpoint the trigger that is causing the effect.
So I imagine I'm testing the white unit with the red reset button right?

Leoni.
