Subject: Pressure getting too high - steaming
 

Hi.  we have had the Cuadra for about 4 years and just had a major service 3 months ago.  we now have a problem with it going very high on pressure and steaming from underneath.  It does seem to go down again.

I have descaled it as the Coffee Machine experts said it might be a blockage - but it happened again straight afterwards.

My husband has been leaving it on all the time and I wondered if there is any problem with that.

But is it just time to consider a replacement?

thanks

There should be no problem with leaving it on all the time.

I would not look to scale for an overheating issue, I would start with the pressure stat, it may need to be rebuilt or replaced. The pstat is the device that controls the temp of the boiler.

calblacksmith is correct. not really sure the scale would result to overheating. let us know what happened after you check the pstat.

It is possible that the relay is sticking closed (Sticking on) due to carbon build-up on the points. If the plastic box is so blackened that you can not see the points inside, it is time to replace the relay.
There are a few threads here about replacing it with a new one as well as well written descriptions of upgrading it to a solid-state set-up.

In addition to everything said already, there's no reason you should have to replace that machine after only 4 years. A little loving care will keep it running well for many more years to come.

Hello again and thanks to all contributors.

we are not very hands on with equipment so took it to our local La Nuova Era repair company.

FYI it was both the pressure stat which they replaced and a worn steam arm/tap which they also replaced.

Working well now.

thanks again Carol
