Good morning all,
I thought I’d cured the fault with the above dishwasher last week, yet, I’ve just received a phone call to say the fault has recurred.
Having visited, and done some research, I confirmed that the fault relates to Aqua Control/Anti-Flood activated.
The drain pump runs continuously, along with the above error code.
I dried out the tiny amount of water in the base, and tested the float micro switch, (fault remains) so, I took a look at the pressure switch, which had water in it, and dried it out.
Reassembled, and all fine…
So, I’m planning on replacing the pressure sensor switch, and wonder if anyone knows how water is getting into it? Porous switch casing, (seal looks fine) sump…?
Regards,jonty

Most common possible causes • This error is caused by water overflow or leakage, and some of the possible causes are listed below. Since water is present and in contact with almost all components of the dishware be aware that a leak may be located in any of those components in contact with water that make the boundary to the exterior of the washing zone (tub included).
• 1 – Water in bottom tray (the visible effect but not root cause)
• 2 – Drainage problem – drain installation (flap not working) water returning back.
• 3 – Leak from the interior lamp
• 4 – Leak from the door gasket
• 5 – Leak from the external nuts of Comfort lift
• 6 – Water or dirt in the level/ pressure sensor
• 7 – Sensor bracket not in correct position (snap-in)
8 – DW is mounted in a way that the bottom tray is pressed upwards by an object or unevenness of the floor.
• 9 – With main board PB200/300 drain pump defective or not connected.Well, I suspect the pressure switch (which I don’t know if it can be tested conclusively?)
If not, perhaps there is a tiny hole in the water sump, allowing water to ingress the above?
