My sr24h hobart undercounter dishwasher is stuck in a mode where all it does is drain water out. Will not do anything else...???

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

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.

Hello Jim Richards,

I tried to pull down... any meaningful information
from the GARDEN VARIETY part houses...

It appears you can get replacement parts through grainger...

Manualslib.com does indeed show SR24H
a commercial grade unit...
(also SR24C... similar chem clean commercial grade)
Hobart SR24C Instruction Manual Page 4
Hoping to find valves, schematics & perhaps
even PART NUMBERS... (no luck).

Found some parts on the internet...

I don't know if you have tried to "activate" the valves
(power direct to... VALVES not responding = open coil)

Or you are having a control board failure
(test for voltage present)...

If you have power at the valves... and they are merely not responding... Some folks will tell you to clean the
(descale.... decalcify) your VALVES.

I'd say replace them... NOT CHEAP
(but it appears "KITS" might be available)
then play with the old ones at your leisure...
(obviously... if that I indeed your issue)

Grainger.com might help (but not obvious on the net)

Vintage NOS Kitchenaid Hobart Dishwasher Water Inlet Valve 4162119 240343 1

You need to calibrate the chemical pomp.

May be the water inlet valve.The screen could be clogged or the valve itself may be bad.

Use a commercial deliming agent (like Lime Away or LSR). Remove the rack from the dishwasher and close the door. Press Off to power down the machine. Next press and hold Wash (Delime) while pressing ON. Delime should show in the display. The unit will fill with water and then flash Add and Delime. Open the door and add the deliming agent according to the directions. (The sump holds about 3 gallons of water.) Close the door and press Wash (Delime). The machine will start the wash mode for 5 minutes and then do two rinse and drain cycles. Delime symbol will flash while this takes place. When finished, the power to the control will be turned off. Check the interior of the machine for lime deposits. If needed, repeat the delime cycle. If the delime program is interrupted before it is completed, then start the delime process from the beginning.

I hope this helps.
