Delonghi DE500p has flashing error code E1 Why and How to fix? I unplugged sensor behind grill/filter on right side and got flashing error codes E2-E1-E2-E1, etc. Replaced sensor and I am back to just E1 so it does not appear this sensor is the problem. It appears E1 has something to do with the measurement of the room relative humidity because it never changes from 90 and the humidifier compressor runs constantly.
