Hobart Code Clarification
Hobart Error Code 22 Help in NYC
If you landed here because your Hobart dishwasher seems to show 22 or E22, the first answer is simple: Hobart commercial dishwashers do not document 22 as an official fault code. In New York kitchens, that search usually starts because a residential code got copied onto a commercial machine, or because a configuration-screen value got mistaken for a live alarm.
This page stays narrow on that confusion and points you back to the real Hobart codes tied to draining, filling, controls, and rinse conditions.

What We Clarify First
E22 is widely documented on some residential dishwashers, but not on Hobart commercial warewashing equipment.
On some Hobart models, the number 22 can appear during programming or firmware inquiry and get mistaken for a fault code.
If the machine has a real drainage problem, the documented Hobart code to look for is E5.
Quick Answer
Hobart commercial dishwashers do not have an official error code 22 or E22, so that search term usually points to a residential Bosch-family code being misapplied or to a Hobart programming screen value being mistaken for a fault. If your Hobart machine is actually not draining, the documented code is E5, and if it is not filling, the documented codes are E0, E2, E3, or E4.
Why People Search Hobart Code 22
These are the documented reasons that number comes up around Hobart commercial dishwashers. The goal here is to resolve the confusion honestly and redirect the diagnosis to the real Hobart code set.
Code 22 is not an official Hobart fault
The first thing to clear up is the code itself. Hobart commercial dishwasher documentation does not list 22 or E22 as an official error code, so the display reading people describe is often being misread or pulled from the wrong machine family.
Residential code confusion
E22 is heavily documented on residential Bosch, Thermador, Neff, and Siemens dishwashers, where it points to a blocked filter or drain pump issue. That residential search result gets copied onto Hobart pages and creates confusion for commercial machine owners.
Programming or firmware menu value
On some Hobart models such as AM Select or LXe series units, the number 22 can appear on the interface during firmware inquiries or while moving through programming and configuration options. That can be mistaken for an active fault even when the machine is not reporting one.
Real Hobart drainage issue
If the machine actually has a drainage problem, the documented Hobart code is E5. The listed causes are a clogged internal strainer pan, a kinked drain line, or a failed drain pump or drain valve.
Real Hobart fill issue
If the unit cannot fill correctly, Hobart uses E0, E2, E3, or E4 instead. The documented causes are closed water valves, clogged inlet strainers, or level probe malfunctions.
Official Hobart Codes to Check Instead
Code 22 itself is not documented by Hobart. These are the real codes and meanings that matter when the machine is actually showing a drainage, control, or rinse-related problem.
E22 / 22
Meaning: Unofficial for Hobart commercial dishwashers and not documented by Hobart as a real service fault code.
When service is needed: Service is needed when the machine has a real operating problem and the display needs to be interpreted against the actual Hobart code set, especially if the screen may be showing a configuration value instead of a fault.
E5
Meaning: Official Hobart drain fault. The control detects that water is not draining from the wash chamber.
When service is needed: Service is needed when cleaning the strainer area and checking the drain line do not restore draining, or when the drain pump or drain valve needs diagnosis.
E6
Meaning: Official Hobart critical control board or communication fault.
When service is needed: Service is needed immediately because this is a control-side fault that requires technician diagnosis.
01 / 02 / 03
Meaning: Official Hobart Centerline codes tied to booster temperature out of limits or a Rinse Assurance error.
When service is needed: Service is needed when the machine cannot maintain proper rinse conditions and the issue does not clear with basic reset and supply checks.
DIY-Safe Checks vs. When to Call a Professional
DIY-Safe Checks
- Performing a hard reset by switching the dishwasher off, turning off the wall circuit breaker for 60 seconds, and turning it back on.
- Removing and cleaning the scrap baskets, strainer pans, and wash or rinse arm nozzles.
- Checking the incoming water supply lines and making sure the water shutoff valves are open.
- Verifying the door is fully shut and not blocked by a rack.
Professional Repairs

- Replacing drain valves, fill solenoid valves, or chemical pump lines.
- Replacing control boards or reprogramming machine configuration settings.
Frequently Asked Questions About Hobart Code 22
hobart dishwasher e22 error code
The direct answer is that Hobart commercial dishwashers do not have an official E22 or 22 fault code in their service documentation. In real calls, that search usually points to a Bosch-family residential code, or to a Hobart screen value seen during firmware inquiry or configuration navigation rather than a live machine fault.
hobart commercial dishwasher not draining
The direct answer is that an actual Hobart commercial dishwasher drainage problem shows up as the official E5 drain fault, not E22. The documented causes are a clogged internal strainer pan, a kinked drain line, or a failed drain pump or drain valve, and those are the areas to check before the machine is put back into service.
