Hobart Commerical DW This machine uses the Hobart pump similar to the motor and pump that was used in the kd18-20 home style DWs. The motor in this machine runs on 120 volts as do the controls, and you could also run the heaters on 120 volts also but it would take four times as long to get the holding tank up to temperature, however this may not matter as you may not be doing back to back loads every 5 minutes like you might do in commercial service. Bear in mind that to run this machine on 120 volts you may still need a 30 amp 120 volt line, although you can sometimes disconnect some of the sump heaters to tailor it to the voltage and wiring you have available, so it would probably be possible to run this DW on a 120 volt 20 amp line.
I have this exact DW at our warehouse and may use it in the future as a parts cleaning machine.

Only the Booster heater Needs 240/60/1 power
The rest of the dishwasher runs on 120/60/1. As John said it would take 4x longer for the booster to reach the NSF required 180F rinse temp at this voltage and it would be grossly inefficent at a much higher operating cost per rack. The machine could do around 8 racks per hour instead of it's NSF rated 17 with proper sanitization as specified by NSF code. If you want to use this DW at home run a 240/60/1 30A circuit to it for proper operation.
That said it is one of the best undercounter warewashers ever made. You will be floored by it;s wash action and durability. WK78 | ||

Hobart Commerical DW Hi Nick thanks for the additional information about this DW, yes and I didn't even talk about the DW much.
One clarification however is that it would cost no more to run this machine on 120 volts than 240 volts. If it were less expensive to run heating elements on 240V you would have seen a shift to 240Vs long ago and when you think of all the things that are being to save electricity these days, simple solutions like this would have been done long ago. | ||

Cycle time
Questions for Stevet, or anyone else....
1. What is the cycle time (start to finish) for this machine?
2. How much does the extra switch on the controls extend the wash time?
3. As this is a "commercial dishwasher" is it just a 5 minute wash time as John L hinted at above?
4. Does the cycle consist of a wash and a rinse or...?
5. Does it have a seperate "rinse water tank" as I believe the really large machines have, or does it rely on heating the water uber quickly?
Thanks!
