Question about Jackson 25 in. TempStar HH Free-standing Dishwasher
I work for a leading chemical company and this problem has haunted 2 Territory Managers trying to fix this issue. In the account we service the motor 2 to 3 times a month sounds like it is surging and that there might be air in the pump. Once we remove the pump and reinstall it all is well surging stops.
Here is what we have already done.
1. Checked the incoming building water pressure which is static and comes in at 20 PSI.
2. Augered the wash arm manifolds to check if there's anything causing the air gap inside the pump housing.
3. Made sure all wash arms are free of debris.
4. Nothing is ever caught in the pump or manifolds.
This customer is getting extremely angry with this machine he's purchased. The only thing we can think of doing is drilling a 1/8 size hole in the impeller just in case air gets caught so that it may travel in back of the pump seal. Since Jackson Tempstar motors have the motor impeller static you are unable to move the impeller forward of backwards to help with pressure.
Can someone offer a solution? We are getting tired of constantly removing the motor check and re-installing.
The pump housing O-ring? Or the gasket that seperate the pump housing and the motor? Or would you mean the impellor/motor seal assembly? I have not replaced that yet perhaps I should give that a try. Could you provide in detail a little more information? Thanks

Hi,im a hobart service tech.couple of things to try (you may already have)--check the wash arms at the seams make sure their not cracked,make sure the drain is sealed and not leaking at all.if the unit loses any water or the wash arms are cracked at the seam the unit will sound like its starving for water.make sure the unit is leveled.next time you go back if its acting up pour a half gallon of water in the tank and see if it runs correctly,if it does you could be losing water or the water fill vave could be acting up and not letting enough water in.let me know.
