What Er22 means
Er22 is a third touch board code on Monogram ZHU30 and ZHU36 induction cooktops. It signals an internal electronic problem on the board behind the glass keys, and a technician reads it in the cooktop's service mode. The owner sees only an E, or an E alternating with a letter. Keys may stop answering and the cooktop may refuse to light a zone. The touch board is the part named for replacement when the diagnosis is confirmed.
Common causes of Er22
- Touch board electronics
- Connector seating at the touch board
- Moisture or residue around the keypanel
1. Make sure all elements are off and the glass is cool. 2. Clean the glass around the keys with a dry soft cloth. 3. Turn off the cooktop's breaker, wait a minute, and turn it on again. 4. Try a flat, dry pan on one zone. 5. Do not keep testing if the E returns.
- The owner display does not show Er22 itself
- We separate a board issue from a damp or dirty keypanel before replacing anything

Other Cooktop codes
Why do I see different codes for the same board?
The board can report several internal checks, and each one has its own number. The technician reads which was stored. It helps us judge how the cooktop has behaved.
Will drying the glass help?
It can if moisture was confusing the keys. Wipe the panel dry and turn power off at the breaker for a minute. If an E comes back, the board needs testing.
Is this dangerous?
The code is about control electronics, not heat. Still, do not keep using a cooktop that behaves unpredictably, because an unreliable keypad can start a zone you did not choose. Call us for a check.
