Sr24h does not rinse - Hobart Dishwashers

There are metering adjustments either inside the machine, or on the pumping unit on the wall. It is a known fact that rival companies will mess with other company equipment and then come along and say they can save you money on detergent and rinse aid.

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.

SR24H

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)

Remove water by checking the drain filter.

Hello.
As per my personal opinion this is normal because for the final rinse you have a small booster or boiler..
When you turn on the machine..it starts fill and also the booster for the final rinse.
You start the machine..wash cycle...rinse cycle..
Now..new water(from rinse booster) is coming on the tank in order to rinse the dishes..on the same time the machine drains the excces water from the rinse(over flowing) and fills up the booster with new water.
Should be like this

Good luck

see the wirin diagram for test and see how to test:

Hello There; If your unit stuck on the wash cycle and not advance to rinse cycle because the rinse water is not up to 180 degree . You've to check out the booster element and the rinse temp. I hope this will help.
