JHCCoffee Read somewhere that pure unmineralized water can cause water out indicators to produce faulty readings.
Not on the Elizabeth! The Elizabeth has concealed float on the left side of the tank. It potentially got stuck.
Take the tank out again and see if the float is moving by emptying the tank and turning it upside down.
The other less likely possibility is… Did you put the tank the other way round by any chance?
In other words, the tank float needs to be on the left side of the machine (same side as the on/off switch).
