- Testing out the old and new solenoid blocks to see if we can find out if this is the source of the problem.
It seems the 2/3 way Olab solenoid is indeed the source of the buzzing sound. Electrically, all the solenoids test out, but that one buzzes when actuated. The new Ceme solenoids see to be higher current/power and have a much more solid sound to them when changing state than the Olab solenoids. It seems Olab solenoids are used in many Breville coffee machines judging by the eBay listings. It looks as if Breville has changed to the Ceme brand lately.

If you're having issues with an RCD/GFCI style breaker/receptacle tripping when running that machine, you can test for a connection between the horizontal ground/earth pin and either of the vertical power pins on both coils. If the plastic housing shows signs of water leaking onto it or it's burnt or cracked, best to replace the coil and if there's a water leak, find and fix that as well.

Thanks for the video. My BES820XL does not pass water/steam at all, so I'm looking at this solenoid/valve assembly and wanting to test it. I hear clicks from the solenoid, but the valve only passes air through one of the short fittings, even when actuated with a paper clip through the outlet (long fitting). This valve behavior does not explain my symptoms, as I would have expected something (water or steam) to pass. Other than the current test you explain in this video, is there another way to explicitly test the solenoid itself? I realize it's a magnetic switch, BTW.
Apply DC voltage to the solenoid. Works without problems. Good luck.
Can you show where you have gotten the Ceme solenoind assembly from, and the part number? (I am also interested in the fittings, too, in case mine break.) I have heard of using non-OEM valves, but until now, knew nothing of who or where they were available. You are correct, as far as getting them from Europe, I ordered some Olab valves, but it takes about a month to come. Thanks.
Hi there. Has my solonoid valve gone bad? I removed my solonoid and tested it. It has 10 ohms (tested with multimeter)
If I am getting no pressure and no water coming out from the cappuccino maker, but I do have steam and hot water for tea. Would it be the solenoid?
Thank for the video. My BES875 trips the RCD breaker when pressing singe/double shot expresso. Steamer and grinder work fine. Resistance on CEME 588 is 2.3 kOhm. I checked machine with Live line disconnected for 2/3 ways valve and it did not tripped the RCD. I will try to replace valve with a new one and have a go.
Great helpful video. I have an issue with my barista express BES870 with no flow at all to water/steam and grouphead. Suspected pump was the issue but this was tested to be good from disconnecting outlet tubing with strong water flow. Removed the 2-w & 3-w solenoid valves, internals checked to be clean no issue. Thermoblock & tubings were checked to be clear with no blockages, Triac and PCB checked with no obvious visible issue on connection or failures/burnt marks. Now cleaning the 3-w valves just to be sure the internals are clear. Measured the resistance of both solenoid coils and both are reading around 2.4 kOhms (2400 ohms). This looks pretty high. Solenoid coil is JLT 0325K unit, 240V, 9-13.5VA. Have the solenoid coil failed ? I couldn’t find healthy resistance reading from the website. Advice is appreciated. Will reassemble after descaling the 3-w valve, then retest. Thanks
What is the value of the magnetic coil ohm?
Nice video. Did you have to replace the valve or could it be cleaned and just re-install
I would appreciate some advice on my 870 Barrista Ezpress Coffee machine. Water stopped flowing completely. I replace with new pump but still no water. Replacing the solenoid i.e. and I guess it would be the 3 way part. Mine is CEME series 588. Where can I get this from? And as long as it is series 588 will it be the same replacement? Incidentally, I do not hear any buzzing noises despite no water flow. Your advice would be appreciated.
Excellent demo, thanks
Excellent demo helped me a lot, I am going to sort mine now.
great videos man!
So awesome. Had the same issue, however the warranty solved! But thanks for sharing!!!
Thanks for the video. My BES870 started malfunctioning a few days ago. I believe the issue traces back to a bad solenoid but I am not 100% sure. I was hoping to get your expert opinion. Here are the symptoms:
Thank you for the video. By the sound of failing coils I could say that I have defective one as well. What will happen if I swap them? I dissembled everything but couldn't get 2/3 way plunger to budge so I can clean inside..I soaked it in vinegar overnight( i know vinegar in not good for rubber seals but didn't have anything else).
Love the explanations, I wish I had the test bench, but you showing the noise on the failing valve will probably help me. I think I have the same noise on a non-disasembled olab solenoid assembly .
Can you send me a picture of the drive circuit on the main circuit board?
Thanks for all the informative videos.
Do you mind letting me know how you disassembled the value from the Olab coil? i can't see to get it off.
