Dreg drawer and descaling light alternately flashing red. What do I do?

SOURCE: dregs light stays on (even when emptied!) - can't use machine

the various lights are controlled by either magnets that hit various sensors or microswitches.

the dreg light i'm pretty sure is a microswitch.

Its pretty common for them to go out, they're standard in almost all super automatic machines.

that particular switch is a pain in the **** to get to. You can order them direct from saeco, but if you can, it may be easier to send it out.

There should be a microswitch for the grind box, for the drip tray, for the water tank, and there should be one if i remember right for the grinder.

Its different for each model.

Hope this helps.

That is serious, that means the grinder is jammed or not working. To check the components of the machine follow these instructions.
Press and hold the steam button and turn on the machine, when you see the lights going around in anticlockwise direction, release the button. Turn the coffee dial to the left and press the steam button, the grinder should turn. Dial on the right and pressing coffee ****. water pump runs. Press steam ****. brew group go up, dial 1/4 to left B/Group down.
If grinder not turning the motor is bad. Hope it will help to find out.

When you press the coffee button , and the top and bottom lights are flashing, that means the grinder is either jammed or out of order. If the machine is less than 2 years old, the service center will replaced it under warranty.

Hi, the problem with your machine is with the grinder motor (not working).As soon as you press the coffee the CPU senses the motor is out of circuit and the lights start flashing alternately.
You can test it by doing this. Press and hold the steam button and switch on the machine, you will see the lights going around in anticlockwise direction. Release the button then turn the dial to left (Min) and press the steam button the grinder should work. The dial on the right (Max) the brew group will come up..and half way it will come back to normal position. Press the coffee button in that position will work the pump. Servicecenter can fix this if the machine is less than 2 year old FOC.
