MEACO DRY ABC 10l DE-HUMIDIFIER : :Fault Code E1

My De-Humidifier is flashing error code E1 and after a couple of hours of Continuous Operation there is only a splash of water in the bottom of the collecting Tank with the humidity display hardly moving from 55%.

According to the MEACO Instruction Manual

Fault : E1

Error Coil temperature error

Display Flashes every 30 seconds

What is happening Unit stills dehumidifies but in defrost

mode only.

As a start , I have replaced what I assumed to be the Humidity Sensor KB 5150 located on the front of the cooler as that seemed a logical start ....but it didn't restore the De-Humidifier to proper working order.

Any ideas please?

Here is a link to the MEACO site for their De-Humidifier Instruction Manuals
