Hobart AM 9T2

[DeanandPam]

Hi, I'm new to the forum and would very much appreciate help. Our church has a Hobart AM 9T2 dishwasher that is quite old and is not used much. Now we have a need for it and it isn't working correctly. The water pressure in the washer is just enough to have the water come out of the wash arms about an inch. The impellor looks good and seems to be firmly attached to the motor. There are no blockages anywhere, I have taken apart the water tunnels/manifolds and have verified they are clear. The pump area has water in it when we fill the washer. The washer has a 3 phase motor. I am not an electrician so I'm wondering if the motor might be at fault. I tried removing the motor by removing the 6 bolts that hold it to the pump housing but I can't budge that puppy. I don't want to beat on it too hard as I'm afraid I'll break the motor and or housing.

Can someone shed light on whether it may be the motor or not AND how to get the motor out if it may be suspect.

Thanks so much, Dean
