What E84 actually means
The machine can't connect to its Wi-Fi/Bluetooth side, so the app features aren't working.
E84 means the washing machine's control panel has lost communication with its wireless (Wi-Fi/Bluetooth) board, the part that talks to the HomeWhiz app. It's a connectivity fault, not a washing fault rain and spin still work normally. Either the internal connection between the boards has failed, or the network setup on the machine needs redoing.
What E84 looks like on a Blomberg washing machine
Most people find this page having searched for what the machine is doing rather than the code itself. On a Blomberg washing machine, E84 usually shows up as one or more of these:
- E84 showing on the display
- Cycle stopping before it finishes
- Machine not working properly
- E84 flashing on the display
- Beeping and showing E84
Recognise any of those? That is this fault, and the rest of this page explains what causes it and what you can check yourself.
What usually causes it
- Loose or unplugged connection between the wireless board and the display board
- Network setup on the machine never completed, or needs re-pairing with the app
- Damaged internal ribbon cable or plug
- Faulty Wi-Fi/Bluetooth board
- Faulty display board (less common)
What you can safely check yourself
Work through these in order. Anything beyond this — panels off, testing parts, anything to do with the wiring — is an engineer's job, and not one to attempt with the machine plugged in.
- Turn the machine off at the wall for a minute, then switch it back on and see if the code clears
- Check your home Wi-Fi is working and the router is on and nearby
- Delete the machine from the HomeWhiz app and add it again, following the pairing steps from the start
- Check the appliance is not tucked so far behind metal or masonry that the signal can't reach it
