Hoover E21 error

[Flintstone]

Hi, I’ve a Hoover Wash & Dry 300 – model code HBD485D2E/1-80 – which has recently conked out displaying “E21” error code. This code isn’t in the handbook but internet wisdom relates it to heater element.

The code appeared after it attempted a particularly imbalanced spin cycle. For that reason I’ve popped the top off in case it was ‘simply’ a case of a wire being pulled out by the drum wanging about violently. Lo and behold…

The end of this wire is stripped – so I can reasonably assume it was intended to be connected to something. The most likely candidate I can find is the unit in the bottom left of the above picture. This unit has a three wire connector for +5V, GND and OUT; and only two wires in that connector. There is a scrap of blue insulated wire remaining in there:

Were I a betting man my money would be on this being the issue – but I’m aware I do not know what this cable or unit is supposed to do.

So, my questions are:
– Is this the right place for this wire?
– If so, how the dickens do I reattach it to the connector? Can’t see how to get the crimping contact out.

thanks in advance,
Nick

Update: the module pictured is the water level sensor (which makes some sense with a three wire connector), and I managed to pop the contact out of the connector housing and reattach the signal wire.

I wouldn’t ordinarily advise fixing apparent mechanical symptoms in an electrical system, but it seemed logical and low risk at 5V. Didn’t go bang when powered back on, but – also has not fixed E21 error code.

To conclude this, a Hoover engineer went straight to the water level sensor when looking up the E21 code. They replaced the connector pictured (I explained what I did) but it didn’t shift the error code. They didn’t have a spare water level sensor so ordered that plus the related circuit board.

Some time later I was informed that the quoted repair avenue was no longer being pursued, and that the machine would be replaced.

So, all I’ve really learned from this is that E21 error code in a Hoover washer-dryer relates to the water level sensor, but fixing the error code may not be as simple as replacing that component.
