Subject: La Cimbali M21 pump problem on starting up after de-scale
 

Hi all,

I recently performed some basic maintenance on my La Cimbali M21 (2008, rotary pump) - a descale, changing the filters, cleaning the OPV. All went swimmingly until I plumbed the machine back in and switched it on. There is no pump noise or indicator light and only the indicator for the heating element lights up. I disconnected the machine immediately not wanting to risk further damage to it.

Given that the boiler is currently empty after having been drained during the descale, could I have tripped the boiler? In which case, how do I proceed? Should I disconnect the heating element and try powering it up again?

Thanks for all the useful suggestions,

Paul

If it is trying to heat up, it believes the boiler is full of water.  Probably crud stuck to the autolevel sensor.
Pull the wire off of the level sensor and turn it on.  If the pump comes on, the sensor needs cleaning.

That is what I did first thing - when I pulled the wire off the autofill sensor, the pump kicked and so I went to work on the sensor. I was a little shocked to see how much scale it had on it and that it had stopped working AFTER I had just done a de-scale. An afternoon spent in a citric acid solution made it all nice and shiny again and everything is back in working order. Makes me a little worried about the level of crud that might be still in the boiler and a good reminder that I should descale a little more often than once a year. Thanks for the useful tip!

best wishes,

Paul
