Question about Solis Crema SL-90 Espresso Machine

1 Answer

SL90 stopped brewing espresso

The SL90 decided this morning not to switch the heating light from red to green. The machine also feels cold to the touch and so I think it is either a broken heating element or thermostat. Any chance I can repair this myself? Where would I get the appropriate parts? And if this is not a home job, any suggestions for a store in LA (Westside)?
thanks a ton!

    Ours just quit heating last week after 4 good years service.  We opened the top and checked the boiler continuity and every other continuity we could think of.  They were all good so we think it is the digital board.  Now we are trying to find one.

    yes, same problem. Not heating. Water IS pumping through the wand but water is cold. Same as other users issue ... light stays red and not turning green (indicating machine ready to brew) ... also want to know if "owner fixable" and/or suggestions for repair close to SF Bay Area, California.

    I too have the same problem. The red light will not switch to green and the machine is cold. Is this a major issue?

    We had same problem today and don't know how to find answer.  Red light won't turn to green, so can't brew coffee.  Top of machine feels warm (heated), but pump won't start.  Our machine was purchased in late '06 and has never given us a day of trouble, until yesterday, when this happened.  I ran water through the steam mechanism (turning dial but without pushing button for steam to build -- i.e., I did what manual instructed for venting steam).  After that, the green light came on and I got a cup of espresso.  However, tried it again today and it didn't work.

    It seems there's 2 problems here. With mine the light stays red but the machine is getting hotter and hotter. All but one of the other comments describe the machine staying cold. I guess solution for the 'cold'  problem will get the heating element working. Solution to my problem will turn the heating element off at the appropriate time.

Changing the control board on a SL 90 Re: Checking and Resoldering bad Solder Joints on an SL90

#1 Phillip screwdriver
Scissors or Wire Cutters
Soldering Kit

Step 1.
Unplug Machine and remove the water tank.

Step 2.
Unscrew and Remove the recessed Phillips screw from the top back of the machine, right where the top of the water tank sits.

Step 3.
With the front machine resting against your chest, so the faceplate does not "pop" out, pull from the back -top of the machine (cup warmer), towards the front. To remove the top of the machine (cup warmer) you only need to slide it forward until the faceplate is vertical (perhaps ¾ of an inch), we caution against bringing it any further forward than this point. This will allow you to remove the top. You may let it dangle over the back of the machine where your water tank sits as it won’t hurt the machine. Take off the faceplate by carefully unplugging it from your power board on the left side of the machine.

Step 4.
There may be a white plastic zip tie that holds down your power board. You can remove this piece using scissors or wire cutters (please be very careful!). Next, slide your power board up and out of the two black metal sleeves. Do not worry about disconnecting any wires, as you only need to look at the back of the electrical board where all the small metal dots are. Notice the picture below as it highlights the solder joints that control the heating of your machine. If any of these look discolored (brownish-black) or is a dull gray (vs. shinny silver) then it is going to need to be resoldered.

Step 5.
If you have a Soldering Kit at home, resolder these three joints, making sure to melt some of the original solder. Once you are finished, put your machine back together and test it.

Cuisinart dc 1200 coffee maker auto start mysteriously shuts off

Sounds like the switches got damp when you cleaned it. Let it dry out very thoroughly before you plug it back in. Then set the TIME OF DAY first, and be sure you pay attention to AM/PM if you are not in the 24-hour mode. Next, set the BREW TIME. Once again, heed the AM/PM or you will have nice hot coffee either 12 hours early, or 12 hours late! (I don't know which would be worse.)

Yes, it is possible that the thermostat tripped or is damaged. If thermostat is not damaged then elements might be damaged.

Red boiler light will not go on. The boiler does heat up.

Open the steam valve when you turn the machine on that will vent out the boiler, keep it open until it starts to hiss slightly and produce small steam bubbles, then close and machine should heat to temp. If that solves your problem then the vent valve needs to be replaced, until then you can turn using the steam valve open trick.

Cold shots

Remove the portafilter and press the brew button is the water that is coming out of the head warm or completely cold? If cold then one of the thermostats on the boiler is damaged.

SL 90 Machine not heating

Hi There are 3 things that could be the problem. 1. The power board on the left rear inside. 2. Heating element is burnt out. Replace the top part of the boiler and order a brew head gasket and replace it at the same time while you have the machine apart. 3. and less likely is the temperature sensor. 2 red wires goes from the board to the top of the boiler.
