Frymaster 3000 Fryer Error Code E22: Oil in Pan Error
OIL IN PAN ERROR (E22) on a Frymaster OCF30 series electric fryer with the 3000 controller means oil may be present in the filter pan. Check the pan and the drain valve before the next filter run. Do not start filtering until you know the pan is empty.
Medium: filtering should wait until the pan is checked, but the fryer can still cook.
What does Frymaster E22 OIL IN PAN ERROR mean?
The 3000 controller expects the filter pan to be empty before a filter run begins, because the pan has to receive the oil from the vat. If it detects that oil may already be in the pan, it logs E22 and shows OIL IN PAN ERROR. The word 'may' matters: the manual says oil may be present, not that it definitely is. The action is to check the pan and the drain valve before the next filter run. Oil in the pan can come from a drain valve that did not seal after the last cycle, a filter run that did not finish returning the oil, or a pan that was not emptied after the last service. Starting another run into a pan that is already holding oil risks an overflow of hot oil, so this check protects people as well as the equipment. No cause list is given in the manual.

Possible causes
Likely causes — what usually sits behind E22 OIL IN PAN ERROR on this control. A technician confirms which one it is before any part is replaced.
- A drain valve that leaks slightly and lets oil slide into the pan between uses
- A previous filter run that stopped before all the oil returned to the vat
- Pan left holding oil after changing the shortening
Safe checks before calling for service
- Let the oil cool, then look at the filter pan and see whether there is oil in it.
- If there is, wait until the pan is cool and empty it following your normal procedure.
- Do not start another filter run until the pan is checked.
- Note whether the drain valve looks closed and tell the technician what you found.
How a technician diagnoses E22 OIL IN PAN ERROR
- Read the code and check the history for earlier drain or filter messages.
- Inspect the pan and its sensing, and confirm whether oil is truly present.
- Check the drain valve for sealing and the handle or actuator for full closure.
- Run a controlled filter cycle with an empty pan and watch the oil movement.
- Repair or replace the valve or sensing only after it has been shown to be bad.
- Hot oil in a pan is a burn and spill risk during emptying and testing.
- Valve and sensing tests happen on a live fryer with oil in the vat.
- Separating a leaking valve from a false detection needs observation of a full cycle.
How E22 OIL IN PAN ERROR differs from similar codes
E22 is about oil already in the pan before filtering; E23 is a different message, a vat that did not empty during filtration.
