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
even PART NUMBERS... (no luck).
Found some parts on the internet...
Parts list (
Rev A, August 2009)
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)
Heritage parts, WhaleyFoodService and Partstown
