Hello,

I have a CBS 2052 that's overflowing from the overflow tubes,if I brew from left side it overflows on right side and vice versa,if I use hot water dispenser the tank refills and overflows from both sides, I cleaned the probe which was pretty limed up but it's stilled overflowing

Thanks.

I am sorry to hear that you are having trouble with your CBS-2052. But I think we can get you taken care of, no problem.
Now you say you cleaned the probe and it was pretty limed up and since this is the case I am wondering it the wall of the tank are pretty limed up as well. If you can take the tank access cover off and look inside the tank. (Be careful, make sure power is off and remember tank access cover will be hot) I am guessing that you will find there is lime build up on the tank wall and this is contributing to the problem. This is because not only does the probe need to be clean so it can conduct but so does the tank.
To test this theory ,using a straight edge screw driver scrap the lime off of the tank until you hit metal. A ½’ square area below the water line should suffice. Then place the access cover over the tank opening turn the brewer on and test. If the problem goes away then I would recommend that you de-scale the tank using Dezcal from Urnex www.urnex.com.
I hope this information is helpful and please let me know if you need any further assistance.
