Question about Saeco Royal Professional Espresso Machine

1 Answer

I have a Saeco Royal Professional bought in 2001. It has been an awesome machine. I changed the boiler in 2005 and replaced the O-rings in 2009. It has been decalcified fairly regularly. Last month, I got a brew group blocked error. After reading online about all the possible problems, I decided to send it to an Authorized Saeco Repair facility. They were nice people who were not very good technicians. They said it was just a brew group micro switch. So the cleaning and servicing of my machine cost $250. After one day the problem came back. The Authorized Saeco Repair facility decided it was now the brew group gearbox. They said it would be another $300 because they did not repair the gearbox, only replaced them. By the way, the micro switch the Authorized Saeco Repair facility sent back with my machine checked out perfectly. So, I opened the gearbox and found broken teeth on both gears. I marked the gear locations and replaced them. The machine was up and running again. About 4 lattes later, the problem was back. I checked the gears and they were fine. I called the Authorized Saeco Repair facility for advice. The owner suggested the gearbox motor might be worn out. I replaced the motor but I it did not help. I removed the brew group and tripped the micro switch to verify that it was not the brew group binding. So any ideas?

Sorry to tell you but Brew Unit Block is usually the CPU or the main board going bad. It is usually caused by a constant drag on the brew unit causing more power going to the drive motor causing the CPU and the main board to heat up weaking the CPU or main board to the failure point. To much coffee going into the brw unit and causing the brew drive motor to work harder to compress the coffee will also do the same. You will have to replace the CPU or the main board. It is usually the CPU.

I just installed a new brew boiler and new O rings in the small plastic spigot. When I turn the machine on I now get message "Brew unit Block and nothing happens. Thanks, William. Can you pls give...

I would check that the green sensor wires that clamp to the boiler are in the correct position on the board. Depending on the age of the machine they could be yellow.

Leak when making coffee

it could be an easy fix. it could be a seal (o-rings) that are old and just need to be replaced. Could be a hose that has cracked (unlikely). That machine has 2 boilers.

Machine stuck in ventilate mode after aborted DESCALING. When descaling tripped circut breaker on the power circuit.

This means you probably have a leak inside. Usually the seals from not descaling enough. The steam boiler is over the power switch and will short the power switch. You can replace the seals in the steam boiler hoses, or tighten the fittings and probably save the machine, but change the water hardness setting in the menu to 4. This setting has saved many machines, but you mest descale your machine when it tells you. This also saves the machine.

Saeco Royal professional is stuck on rinsing and warming up. Although the screen says this, it is actually doing nothing that is apparent. Thank you

Couple of things will cause this.
You have a bad board or the sensor on the back of the boiler is bad or not making good contact with the board. Its the double green wires, that go from the sensors unless you have one of the new machines that has the double yellow wires.

Saeco royal professional excesive hot water and steam though capp

These machines run water through the boilers and is heated to either 192 degrees for the main boiler or 250 degrees for the steam boiler. There is mineral in all water except distilled. That mineral deposits itself inside you boilers and needs to be removed. I guessing that the water hardness in your menu is set on 1, but should be set on 4. You need to descale more often than not enough or you get what is happening to you right now. I am hoping that a good descaling will do the trick, but it might take 2, that it needs. Use a commercial descaler for espresso machines, not vinegar which will leave a taste for about 2 weeks.

Magnetic valve


It can be a wire that has loosen to the rapid steam boiler or the boiler that has to be replaced.

Try first to descale the machine to see if that helps.

I had the same problem with a Saeco Royal Digital. I ran the decalcifying liquid through the machine with the automatic descaling program as per the instructions on the bottle and the DECALCIFY message stayed up.
I solved it by going to the menu and selecting "Signal Descal." and toggling it from No to Yes. I escaped back to the menu and git the usual "Select Product".
Hope this helps.
