FAULT WITH DISHWASHER

Replace it with new.

Fault Code F5
Dishwasher Spray arms are clogged or otherwise malfunctioning
F6 Fault code
Dishwasher doesn't detect any incoming water despite the water inlet valve being open.

Fault Code F5 or Five Flashes
Cause: Spray arms are blocked/clogged or otherwise malfunctioning.
Action: Spray arms are easily removed so take them out of the dishwasher and wash in the sink to clear out any gunk (using descaler should help shift any stubborn debris). Whilst doing this run the dishwasher on a short program without the spray arms to clear any further blockages.

FB (or 12 flashes) - Motorised diverter valve. The dishwasher diverter valve controls the flow of water to the upper dishwasher spray arm. If it is faulty it will need checking and possibly replacing.

water is not circlating, you need a circulation pump

In my experience, you probably have a clog in the spray arm/arms for the top rack. Take the arm(s) out and see if the holes in them are clogged. Rice, plastic wrappers, and glass from dishes that broke in there are the most common culprits I've seen.

the plastic screw is not holding it down. First disconnect the white tube in the back of the bottom spray arm.Now turn the stub part clockwise. and the spray arm should pop off...

if its not letting in enough water then this can happen.check water connections or a motor fault.

What flashing are you referring to ? This could very well be a fault code.

there should be a clip half way up the back and on the top. release those and the old tub should come out with out to much difficulty. the peice that attaches from the feeder arm to the lower spray arm turns clock wise and lifts out. the lower spray arm will unscrew if you use a pair of pliers.
