While it’s doing all that blinking and humming:
- Take off the reservoir lid.
- Grab hold of the reservoir with one hand and pump the tank up and down (basically lift the tank up a little and bring it back down, over and over).
- At the same time, with your other hand, cover the overflow elbow plastic tube at the top of the reservoir. You’ll feel a slight suction the more you pump.
- Hopefully one or both of the cup buttons are lit-press one when it’s trying to pump the water through, cover the elbow again here and there to create suction. Water should flow through where the coffee goes.
This is the model with just two size cup options, power and auto off buttons, and lights for add water, descale, and heating.
When turned on, it would hum for a while before any other light would come on. When it did, add water, heating, and one cup light were blinking. Water would not pass through.
Cleaned out the needle part with a paperclip.
Opened the top part and squeezed the tubes in case there was blockage.
Pressing auto off and power button at the same time.
All the tips and videos I could find, etc, but maybe they all helped contribute to fixing it but it wasn’t until I pumped the reservoir AND covered the elbow that it worked.

This may or may not help...
There is an internal check-valve that shuts the pump off if it senses back-pressure. Some people have success just squeezing the internal check-valve to break up calcium clogging it.
(I thoroughly cleaned my own out like this guy did, but you may not want to go that far.)
I removed the reservoir, took a butter knife wrapped in a piece of paper towel, and pressed/jiggled the bottom thingy (that the reservoir sits in and senses water). Bingo! Coffee again.
