Henny Penny Fryer Error Code E-15: Drain Open or Switch Problem
E-15 on a Henny Penny Velocity pressure fryer says the drain is open while the fryer is on, or that the drain switch is not reporting properly. Make sure the oil is cool and close the drain with the valve handle, then switch the fryer off and on. If E-15 still shows, call us to check the drain microswitch.
Medium: the fryer will not heat until the drain reports closed, and the cause is often a simple handle position.

What does Henny Penny error code E-15 mean?
The control will not heat a vat it thinks is draining. A microswitch tied to the drain valve tells it whether the valve is closed. When that switch reports an open drain while the fryer is on, the control stops the heat and shows E-15, because heating with oil running out would be dangerous. In many kitchens the cause is simply a drain handle that has not been pushed fully closed after filtering or cleaning. Behind that, the switch itself may be out of alignment, the wire to it may be damaged, or oil and debris may keep the valve from seating all the way, so the switch never closes. The control cannot tell a truly open drain from a switch that is not making contact, so both look the same on the display. A drain that looks closed can still miss the switch. The display text is E-15, and the maker lists the valve handle, the microswitch and its wiring.

What you may notice
- E-15 on the display
- Fryer will not heat
- Drain handle that looks closed but not fully seated
Possible causes
Listed in Henny Penny's documentation
- Drain valve handle not fully closed
- Drain microswitch out of alignment
- Damaged wire to the drain switch
- Oil or debris keeping the drain valve from seating
Other likely causes — what usually sits behind error code E-15 on this control. A technician confirms which one it is before any part is replaced.
- Hardened oil around the valve stem that keeps the handle a few degrees short of closed
- A microswitch bracket knocked out of position during pan removal
Safe checks before calling for service
- Make sure the vat is not being drained and that the oil is cool.
- Close the drain with the valve handle, as the owner's manual lists.
- Switch the fryer off and on again.
- If E-15 still shows, the drain microswitch needs checking, so call us.
- Never open the drain on hot oil, and tell us whether the handle felt loose.
How a technician diagnoses error code E-15
- Confirm E-15 and check the drain valve position with the oil cool.
- Inspect the valve seat and stem for built-up oil that stops full closure.
- Check the microswitch alignment against the handle's travel.
- Test the switch with a meter, operating the valve by hand.
- Inspect the switch wiring for heat damage or breaks.
- Replace the switch or wire only after the valve is confirmed fully seated.
- The switch and wiring sit under the vat near hot oil lines, so they are handled only when everything is cool.
- The microswitch and wiring have to be tested in place with a meter, which is not an operator task.
- Opening the drain with hot oil in the vat could cause a serious burn, so the valve is tested only under controlled conditions.

Related Henny Penny fryer error codes
The handle looks closed. Why E-15?
A drain can look closed and still miss the switch, so the switch needs a check.
Can I bypass the drain switch?
No. It prevents heating while the drain is open.
Will E-15 clear on its own?
Only if the handle was the cause. Otherwise it returns at the next heat call.
