Model SHS5AV55UC/22. Why does sanitize light blink continuously?

SOURCE: Kenmore dishwasher, model 665.170 344 01. "Clean" light keeps flashing and will not stop. Have tried everything in the manual and the light still will not stop flashing.

If the clean light flashes 7 times, pauses then repeats...

If the dishwasher doesn't sense a water temperature increase, it will stop working and lock the functions (clean light flashes 7 times, all buttons are non responsive).

To resolve this you will have to reset the console. Do this by closing the door and press these buttons in sequence...

-high temp wash
-heated dry
-high temp wash
-heated dry

...all the lights will turn on briefly and the machine will start a diagnostic cycle. You can press cancel or let the diagnostic cyle finish (1-2 minutes).
You should now be able to run the dishwasher as normal.

If the issue returns, you could have a problem with the heating circuit (ie. element, thermostat or wiring). It rarely happens but it could also be the door switch not engaging properly when the door is closed (slightly bend the door latch down making sure it doesn't hit the door when you close it).

SOURCE: bosch dryer lint light flashes

My Bosch Nexxt electric dryer had the same problem with the lint filter light blinking and the dryer not running. It turned out that the door switch was not engaging. The service technician informed me that there is a plastic tab (available only by opening the top access panel) that was not fully snapped in place. When he snapped the tab back in place and then secured it with a screw, the door switch fully engaged, the lint filter light went out, and the dryer ran perfectly! I hope that helps you!

I had the same problem on a 5 year old model. It was the main pump leaking from a perished seal causing the water protection microswitch to trip. This gives the symptoms you describe exactly. Parts cost from Miele was about £60 for a new seal. Fairly easy to fit.
