Greetings all,

I have a Lelit PL62s. I descaled last night using Durgol Swiss - everything went according to plan, I flushed the machine thoroughly afterwards, brought the unit up to temperature/pressure, verified that everything was good, and shut down. Upon powering up this morning, the boiler relief valve appears to be stuck completely open - it's pumping steam into the reservoir like it's the machine's job. We're not talking weeping by, but fully open - it will not build any pressure.

Thoughts?

Thanks in advance.

Brad

Hopefully, you forgot to reconnect the water level sensor wire on the top of the boiler.

If that be the case, you will need to syphon ABOUT 1-1/2 cups of water from the boiler and then let the autofill sensor set the proper level.

Unfortunately, that's not it - as I said, it was functioning completely properly last night after descaling/flushing. The only thing that happened between now and then is that it cooled all the way down.

Thanks, Brad

Sorry . . . I missed that.

The only obvious course would be to remove the safety valve and verify that it is, in fact, stuck open. From the pics I have seen on the 1st-line site, it appears that the valve can be disassembled and, perhaps then, a cause will be seen.

Are there any updates on this?

Was told by manufacturers that running descalers through the pump does many damages and may not do a proper job
