hi, hoping someone can suggest how to troubleshoot this problem further, I’ve already read other topics here and tried those suggestions but it hasn’t fixed my problem.
Breville model BES920 dual boiler bought in December 2017
Symptom: when we open the valve for the steamer wand, it beeps 3 times and just spits out a very light steam with no real force. We have not recently descaled, and have never had a problem after descaling.
Based on the below troubleshooting summary, any idea what might be going on?
Troubleshooting so far:
**is the board setting the boiler to the wrong temperature?**
Used the reset feature, and checked that the wand boiler was set to 275 degrees
**is there a blockage in the wand, or between the wand and the boiler?**
* Took the end off and cleaned it
* Removed the wand from the body, checked for any sign of corrosion, scaling, or blockages (found none)
* Opened the case, pulled out the connection between the boiler and the wand. No blockages found.
* When I turned on the machine with the case opened, I noticed steam escaping from where the wand hose attaches to the boiler; opened it and replaced the o-ring. No more steam escaping, but wand still shows same symptoms
**Is the boiler coming up to temperature?**
I can't be certain, but it is getting hot to the touch, steam was escaping from one gasket (until I replaced the O-ring, see above) and water is bubbling up through the tube connected to the center of the top of the boiler
**Is the boiler filling with water?**
Yes. Ran a test where we disconnected the red wire, which I believe manages the water level sensor. Opened the wand and turned on the machine. Pump ran to fill the boiler with water. I let it run until water started coming out of the wand, then turned the machine off.
**Is the water level sensor calling for water?**
I then drained the boiler, reconnected the sensor, and turned the machine back on. The pump started and kept running until it was refilled. I waited until a few minutes after the espresso boiler came up to temperature and checked the wand, but the wand still shows the same symptoms.
