weird high pressure after water pressure regulator install

Post by cofex » Wed Nov 13, 2019 9:35 pm

Hi,

I have a La Spaziale Dream plumbed in on the water from the fridge 1/4 line. I used it without an water pressure regulator for 3 years.
The pressure on idle is reading 4.2bars.

I installed a water pressure regulator, in fact I installed 2, just to make sure,
Watts 1/4 LF 263A and Watts 1/4 LF560G

During usage, the water is around 1.5 bars, goes to 9.5bars when I run an espresso shot and goes back to 1.5 bars

When I start the machine, the water pressure goes to 6-6.5 bars and throws an alert for high pressure. it stays on 6.5 and it goes slowly down to 1.5 after the temperature gets to be stable, in around 10 minutes.

From reading through the forums it seems the pressure regulator is supposed to let some of the initial pressure to be absorbed back into the house water pressure. Not sure. Both regulators are Watts, are supposed to be good.

The questions I have:

1. Is this normal?
2. Should I stop using a pressure regulator given that the machine is stable without one?

Thank you...

If I read your signature block correctly, your machine is running SW version 1.20. I have version 1.24 on mine but there may be an even later version. At any rate I think ver 1.24 addresses the issue you are seeing.

You may want to contact your machine supplier to see if they have a newer version they can get to you.

Thank you Chas,

I called Chris coffee

they said, the issue is well know: the sensor is too delicate and triggers for any big pressure variation.

At the start of the machine, the sensor detects water pressure change and triggers an alert for high pressure.

This is an issue with a lot of La spaziale machines.

They said to upgrade to the latest firmware 1.24, and to disable the water sensor.

other than that: they suggest to set the preinfusion to 3 seconds and 25 psi and 9 bars for the espresso.

I hope this info helps others.

Thank you for your help.
