Dishwasher upper spray arm not turning despite water flowing

Usenet · 2010-02-07T00:03:04+00:00

Hi, I have a Beko "DE 2541 FX" slimline dishwasher. The upper arm is not turning/spinning/rotating, even though water pours out the spray arm's holes. I have thoroughly cleaned the entire dishwasher compartment: the door, the inside walls, the sump and filters, the upper and lower trays, the arms, just about everything. Now the bottom spray arm works fine, goes merrily round and round spraying just dandy. If I give the bottom spray arm a good flick of the thumb, it spins freely and will do nine or ten complete revolutions until it stops. The upper arm is harder to turn, I can get it to rotate two or three times at most. I couldn't really say under oath that it turns "freely". Should the upper spray arm rotate more freely? The two arms are differently designed. The bottom spray arm is simpler -- it's all plastic and just "clicks" into position. The upper spray arm is slightly more complicated. The central hub is formed of three interlocking snap-together parts: 1) the long arm; 2) the bayonet-lock disc with o-ring; 3) the centre hole piece. The upper spray arm has a bayonet/"screw on" way of being attached. When I cleaned the upper arm, I had to pull out six or so hairs that were wrapped around the bayonet disc and centre-hole piece that form the hub. When the arm is assembled at the factory, the centre-hole snaps into the arm -- trapping and securing the bayonet-lock disc -- in such a way that you can't get at the snaps again to disassemble it. It makes it a bugger to clean the hub of hairs that have gotten wrapped around there! I have soaked the upper spray arm in hot vinegar for 12 hours. **** If anyone has a Beko dishwasher, I would be most grateful if you could post the results of flicking the upper and lower spray arms on your machine. (Be prepared for a few drops of water to fly out!) How many complete revolutions does each do when you give a good flick with the thumb or finger? ****With kind regards,Sandy

Quit using the tablets; use powder.

Pour the contents of the box of diswashing powder in a large bowl, add

10-15% (by weight or volume) of TSP.

Mix well.

Return the mixture to the box.*

Also sold under the name of 'sugar soap' for decorating purposes in UK and possibly elsewhere.

AFAIK sugar soap no longer contains TSP.

Mine runs to the septic tank so it should make the little buggies grow well :)

It works! Or at least the first dose made a big inroad in cleaning it up. I'll run an 'empty' load tonight.

Thank's again to all of ya.
