What Your Machine Is Actually Telling You
E4 means the pressure switch detected a water level above the maximum safe threshold. The board immediately stops filling and activates the drain pump to prevent overflow.
Why overfill happens:
1. Leaking inlet valve (40%) — the solenoid valve doesn't fully close when the board cuts power. Internal rubber diaphragm worn or gate stuck. Water seeps in slowly even when the valve should be shut.
2. Pressure switch failure (20%) — the switch reads incorrectly low, so the board keeps filling.
3. Pressure switch air tube blocked/kinked (15%) — gives false low readings.
4. Siphoning (10%) — drain hose positioned too low, allowing water to flow back from the standpipe.
5. Board fill relay stuck (10%) — relay contacts welded closed, continuously powering the valve.
6. Water entering when machine is off (5%) — leaking valve allows water in 24/7.
The danger: An overfilled washer can overflow the tub and flood your laundry room. Front-loaders are especially vulnerable because the door seal has a maximum water height it can contain.
Critical first action: If you suspect a leaking inlet valve, turn off the water supply taps behind the machine immediately. Water will continue to enter a leaking valve as long as the taps are open, even with the machine powered off.

What You're Probably Seeing Right Now
- Water level visibly higher than normal in the tub/drum.
- You found water in the tub when the machine was off — it filled itself.
- The drain pump is running continuously — the board is trying to remove excess water.
- E4 appeared in the middle of a fill — the board detected overshoot.
- You hear water slowly trickling into the tub when the machine is idle and taps are on.
DIY Fix — From Easiest to Hardest
1
Turn Off Supply Taps Immediately (30 seconds)
**First priority — prevent flooding:**
1. Go behind the machine.
2. Close both hot and cold taps.
3. This stops any further water from entering.

2
Check the Drain Hose Height (2 minutes)
Rule out siphoning:
1. The drain hose loop should be 30-36 inches above floor level.
2. Don't push the hose more than 6 inches into the standpipe.
3. If too low, water from the drain can flow back in.

The Off-Machine Fill Test (30 minutes)
**Critical diagnostic — is the valve leaking?**
1. Run a drain cycle to empty the tub.
2. Turn the machine **off.**
3. Turn the taps **on.**
4. Wait **30 minutes.**
5. Check the tub. If water accumulated — the **inlet valve is leaking.**
**If water appeared:** Keep taps off. Replace the valve.

Check the Pressure Switch Air Tube (10 minutes)
If valve doesn't leak but E4 appeared during a cycle:
1. Unplug. Access the pressure switch (top or side panel).
2. Follow the thin air tube from switch to tub.
3. Check for kinks, cracks, blockages.
4. Blow gently through the tube — should hear bubbling at tub end.
5. Clear any blockages.
**Water or suds in the tube** = false readings. Clear and reconnect.

Test the Pressure Switch (5 minutes)
1. Disconnect tube from switch.
2. Blow into switch port — listen for a click.
3. Release — another click.
4. No click = dead switch. Replace ($15-40).

Replace the Inlet Valve (20 minutes)
If valve is confirmed leaking:
1. Turn off taps, unplug.
2. Disconnect hoses from valve.
3. Remove valve mounting screws.
4. Disconnect wiring.
5. Install new valve — match to model number.
6. Reconnect all connections.
7. Test with normal cycle.
**After repair:** Consider closing taps after each wash as Bosch recommends. It prevents flood risk from future valve failures.

When to Call a Pro
- •Valve confirmed leaking — replacement: $100-$220.
- •Board fill relay stuck — board repair or replacement: $150-$400.
- •Pressure switch failure — replacement: $80-$180.
- •Flooding occurred — check for water damage to flooring and subfloor.
