Hello Karim;
My name is Peter. I am a retired field service appliance technician.
You have a expensive transmission drive dishwasher. Next time do not buy a transmission drive, then you may be able to access and replace parts yourself.
So, here are the parts and parts cost:
1.) Dishwasher Pump Assembly. Part cost: $170.00.
2.) Dishwasher Sump. Cost: $37.00.
3.) Dishwater filter. Cost: $65.00
4.) Dishwasher Mesh Filter. Cost: $27.00.
So, lets say I am not retired from Sears Home Services and I came to your home on this service call.
Standard charges are the cost of the part marked up to twice the part cost. Labor for this job, several hours would be about $300.00+.
Do not call a service company. You are looking at a repair cost of over $700.00.
Purchase a new unit. Not transmission drive. Search; "Sears Outlet Stores". These are scratch and dent stores. You can save several hundred dollars and receive a one year warrantee. Stay away from transmission drives, LG & Samsung units.
Peter,
