20 Most Recent Hobart 120/240V SR24H Undercounter Hot Water Sanitizing Dishwasher with Detergent Pump Questions & Answers


Full parts list here, but from my 52 years in the hospitality trade, Hobart washers need professional diagnosis and repair. Your unit has a 'Chemical Detection Box', but only the engineers will know how or what it detects.

also see page 6, items 17 and 18, and 20 Timer Relays. Part 17 is specific to detergent and rinse, so replace that first.

CTRL+F shows the machine has 7 relays

There is no electricity generating into the device.

It's a guess, because I haven't used Industrial Hobarts for a while, but the contactor unit for the pump is faulty. These are usually hidden behind the control panel or the bottom kick panel.

ONLY YOU CAN CHECK THE WATER INLET

Check water pressure, check valves, unscrew connection at the unit and check for debris screen that may be clogged. If that does not work then you are looking at troubleshoot the actual valves to see if they have failed or are having a power issue.

I suspect that you have something in the wash pump. It might have gone through the filter or when you cleaned the base filter, it dropped down the hole.

I suggest that you search on youtube on:
REMOVING OBJECT FROM A HOBART WASH PUMP

On removing objects from a dish washer pump, you will need to pull mains plug out gain access to wash pump. Then, use a screwdriver in back pump shaft. Turn and you will feel if there is something in pump and sometimes you can vacuum out through base filter using a wet vac.
Hope that helps.

If you see F04, it is likely that there is water inside the air trap or pressure transmitter for wash tank is faulty. Sometimes it happened due to water inside pressure pipe.

Sounds like pressure sensor, most likely the wash tank level sensor air trap blocked.
