I have a Reneka Viva espresso machine 2 group. I got it a few months ago descaled it, and today fully assembled it. (Prior to me purchasing the machine, it was sitting for a long time).
Anyways, the problem is that I have no pressure, there are two pressure gauges, one is for brew/steam pressure and the other is pump pressure. The pump pressure works fine whereas the other one doesn't budge from 0 bar. When the machine is turned on, after a little while (2 minutes) all lights on the buttons start flashing, which I assume is because of no pressure.
The water pump is a rotary pump; and pressure switch is made by Sirai (which I dont know what it's for, the pump or the boiler). It's really frustrating, please help me.
All the buttons are functional but when the green lights start flashing, pressing buttons does nothing. You have to restart the machine (on -> off -> on) to use the button but then green lights avail again.
Hi and welcome to the board. The Pstat (Sarai) maintains steam pressure in the boiler, it is your temp control device for the machine. Your brew water passes through the steam boiler to heat, if the steam boiler is too cool or too hot, your brew temp will be off.
Did you try to power up the machine before you did the work? I t would have been nice to know if the problem is a new one or one that was there when you bought the machine.
Have you filled the boiler? It sounds like the machine is going into the safety mode, this happens when there is not enough water in the boiler and when the machine senses this, it shuts down to protect it's self, some machines sound a buzzer some flash lights, some do both and in any situation, the machine will not function, it shuts it's self down.
Your gauges are normal, one reads boiler pressure (temp) the other reads brew pressure and will be 0 unless you are connected to city water (which you should be) then it will read city water pressure on the low side and it should show about 9 bar when brewing. With no pressure on the brew gauge, I am wondering about your city water pressure.
I can't go to your pictures, the firewall/virus protection software will not let me go to your storage site.

Sorry for the late response. You are right, it was going into safety mode. There is basically a safety time out feature to avoid the machine filling too fast. I was advised by the manufacturers to switch the machine on and off (5-8 times) and that will fix the problem. And it did. Once the boiler is full it works just perfectly.
