ASKO Tumble Dryer Code E9: Software Versions Do Not Match

Medium · inspection needed

Code: E9
Appliance: Dryer
Brand: ASKO
Warranty: 30-day workmanship

What E9 means

E9 on ASKO T5 series tumble dryers (TD86 platform, among them the T5HXLW.U), means the software on the power board and the software on the user interface are not compatible. The two boards must run matching versions to work together. When they do not, the dryer cannot run a program and shows E9. This usually shows up after a board has been replaced.

Common causes of E9

Software on the power board and the display board that do not match
A recently replaced board with a different version
A board whose software did not load correctly

✓ One safe check you can try

1. Turn the dryer off, pause briefly, and turn it on once more. 2. Hold the OK button to read the description if E9 shows. 3. If the dryer was serviced recently, mention it when you call. 4. If E9 returns, stop running the dryer and book a visit.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

E9E9 questions

What do PB and UI mean in this code?

PB is the power board and UI is the user interface, meaning the display and controls. E9 means their software versions cannot work together, so the dryer refuses to run until the match is restored.

Can I fix E9 myself?

A restart is the only owner step and rarely clears it, because the mismatch is stored in the boards. It needs a technician to correct it.

Can you repair an E9 error?

Yes. Our visit starts when you call us or fill out the online form. We give a written price before any repair, and each repair is covered by a 30-day workmanship warranty.
