    Thanks for the advice. The motor finally seazed due to completely rusted front bearing. Cleaned it, but the machine wouild not start ("clean" light is flashing and the "start" button produces three flashes indicating the the cycle heas not been completed and the door not opened - opened the door but to no avail).

    How do I fix that?

It could very well be the wash pump motor starting to fail. It could also be something as simple as food and debris clogging the intake to the pump. The main wash pump is used to circulate water during the wash cycle. If the intake to this pump is clogged with debris, it can exhibit louder than usual noise during operation and lower water pressure. This particular model also has a chopper assembly just prior to the pump intake. This chopper can dice up some food particles, but cannot process things like popcorn kernels, tough pieces of meat, celery, etc. Basically, anything hard, fibrous, or tough. If you go to searspartsdirect.com, theres an illustration of the pump assembly under the "Pump and Motor Parts" heading. The chopper is item(s) number 6 & 8. If anything gets caught in the chopper it will not provide enough water flow for the main wash pump. Double check the pump sump reservoir and make sure it is all clean. If it still exhibits the same symptoms, the motor may be damaged. I hope this helps you. Let me know if you need further assistance.

When washer is started make loud grinding noise


Very likely the bearings in the motor have begun to fail. You can replace the motor, but for a 15 year old DW, sometimes it makes better sense to just buy a new one. Depends on the features the old DW has, vs new, vs motor replacement cost.

Makes growling noises throughout the cycle.


HI. here are the most common issues that will cause a noise during the wash.

* Check the spray arm for damage and obstructions
* Check the inlet filter screens
* Test the water inlet valve(see below for test procedure)
* Check the motor and mounts- The motor may e loose or one of the mounts may have separated form the housing. this will cause mis-alignment.
* Check the fan motor and blade
* Check the drain for obstructions


NOTE

If all checks out above, the culprit will be a cracked pump impeller. this will occur if the drive stud becomes unstable, allowing the impeller to partially separate form the motor spin drive stud. this will cause the impeller to rub or grind during the wash cycle. If this is the case, there are impeller repair kits available for purchase that will correct this issue.

Load grinding noise, like the engine is working too hard.


Most likely the motor/pump assembly is worn out and grinding. If the machine is less than five years old it is under warranty. If over five years old, the repair part alone is about $150 not including labor.

A noise could be created by something getting down into the motor-pump assembly piece of glass, piece of bone, wire tie anything really. If this is the case and you can remove it before it causes further damage problem solved. At ten years old the problem may be the motor and or pump one thing to consider before putting money into it is disheashers average 7-10 years these days. Good Luck.
