Blocked wash arm error

Hi, any help greatly appreciated. I keep getting an error of a blocked arm after the unit has gone through 1/3 of the time, I restart the wash and it comes back after about a minute till the end.
I’ve replaced all of the wash arm parts and the reed sensor. I’ve run the machine with the sensor unplugged and even put a short on the return leads and the problem remains the same. Is there a replaceable receiver from the reed on the control board or is it intergrated into the board.

[SIZE=3]Have you replaced the little bearing #544 on you motor parts breakdown because that is the part than normally causes this problem. Also is the washer getting enough water because all the error code indicates is that the wash arm isn’t turning enough rpms and lack of water will cause this. [/SIZE]

Yes I’ve changed the bearing. I discovered the little packet info sheet with a diagnostic sheet, it also says to check the sump area. I’ll do that soon and let you know. Thanks for the reply!

Thanks applianceman, I cleaned out the sump area and found broken glass, chips of dishes and alot of slimey stuff. This time it ran almost to the end at the last 2 minute mark it gave me the error again. I’ll take it apart again maybe something dislogged and got hung up. What ever it is it’s alot better than it was. It was going off near the beginning of the cycle and then every minute!
