What E91 means
E91 is a Communication Error on Electrolux Wave-Touch and IQ-Touch dryers such as the EIED55HIW, EIGD55HIW, EWED65HSS and EWMED65HIW. The control board and the interface board, which holds the buttons and display, are not talking properly. The chart lists wiring, the control board or the interface board as the causes. The panel may be blank or the dryer may not respond at all.
Common causes of E91
- Wiring between the control board and the interface board
- Interface board
- Control board
1. Close the door fully and press the power button. 2. See whether the display responds. 3. Do not open the console. 4. If E91 persists, call us.
- We check the connections first, and only then decide whether a board needs replacing.
- We test both boards in the chain.
- We say plainly when a repair is not worth it on an older dryer, and you approve a written price first.
Other Dryer codes
Which board is bad?
We do not know until we test. The wiring may only be loose.
Why is the panel dead?
The interface board has no link to the control board.
Will it come back after a power loss?
Sometimes a glitch clears. If E91 returns, there is a real communication problem.
Still seeing E91?
A technician diagnoses it on site and gives you the price in writing before any work starts.
