Pressure switch

Today’s bit of fun was fixing the PE error on our LG Fuzzy Logic 5.5kg WF-T552 3 step TurboDrum top-loading washing machine.

Apparently the PE error means there’s a pressure switch problem. The pressure switch is in the controller, but connected to the washer drum by a hose. Given that draining and wiggling it wasn’t working any more, and armed with the above information, a light, and a few screwdrivers, I bravely went once more unto the breach.

Here is the inside of the machine. Note the clear pressure hose at the upper right.

The switch is in the controller on top of the machine, and the hose runs down to the outside of the drum. There it meets a channel of some sort, which opens out at the very bottom of the drum like so:

Presumably there’s a blockage in the hose, in the channel, or in the opening at the bottom of the drum. To fix this, you don’t need to open any of the above! Instead, open the cover on top of the machine, like so:

The pressure switch is the component with the circular blue surround. It’s held in by three plastic retaining clips. The hose connects underneath it.

To fix it, I simply released the pressure switch, disconnected the hose, blew hard through it a few times to clear any blockage, and replaced it. We shall see over the next few days whether that is enough to solve the problem!

Update: It worked for a while, but the pressure switch was on the way out. I’ve since replaced it – very easy, and it only cost NZ$20.55. Yay! Big shout-out to Axial who were splendid in identifying and supplying the part.

But will check out pressure switch as turning off at power point must reset pressure switch but don’t like my chances of turning off at power point working every time
