Step-by-Step DIY Fix Guide
- SAFETY: Turn off and unplug the washer before moving the hose or checking the outlet path.
- Inspect the drain hose behind the machine and straighten any kink or crush point.
- Check that the hose end is positioned at the correct height for your Bosch installation rather than pushed too high or too deep.
- Confirm the standpipe or sink drain path is not backing up during drain.
- If your model has a user-accessible pump filter, clean that next before retesting the washer.
- Run a short drain or spin cycle to confirm whether E:30 / -80 clears once the hose path is corrected.
If E:30 / -80 comes back after the hose checks
- If the hose path is correct but water still drains slowly, the pump filter or pump may still be restricted.
- If the drain path backs up at the standpipe, the household plumbing side may be contributing to the fault.
- If the washer drains some water but not all, compare whether the hose routing changed recently or the machine was moved.
What This Error Means
Bosch washing machine error E:30 / -80 means the washer cannot move water out through the outlet path the way it expects to. This is often more about hose setup and drain routing than about a failed pump.
The first things to check are still the outlet hose behind the washer, the standpipe or sink drain connection, and whether the hose is installed at the correct height for your Bosch model.
If the hose path is correct and the washer still will not drain, the next likely issue is the pump filter or drain pump.
What users usually notice before this code
Bosch washing-machine warnings like this often appear after a fill problem, a drain slowdown, a badly balanced load, or a startup sequence that did not settle cleanly.
Common misdiagnoses
- Assuming the display code proves one exact failed part before the safe first checks are done.
- Blaming a pump or valve first when a blocked path, filter, hose, or household plumbing issue is still possible.
- Replacing a lock or latch too early when alignment, trapped laundry, or startup conditions may still explain the warning.
Most Likely Cause by Symptom
The washer drains slowly and may leave water behind before spin.
Likely cause: The outlet hose or household drain path is restricting flow.
Check first: Inspect the hose routing and standpipe height before assuming the pump is bad.
The code appeared after the washer was moved or reinstalled.
Likely cause: The hose may now be kinked, crushed, or routed incorrectly.
Check first: Compare the hose setup against the Bosch installation guidance first.
Common Causes
- The outlet hose is kinked, crushed, or blocked.
- The drain hose is routed too high or incorrectly.
- The standpipe or sink drain path is partly restricted.
- A hose extension or setup issue is slowing drainage too much.
- The drain pump or filter path is also restricted.
What Not to Do
- Do not keep retrying spin cycles while the washer is still holding water.
- Do not ignore a hose that is routed much higher than the installation guide allows.
- Do not assume the control board has failed before checking the hose and drain setup properly.
Model and Display Variation Notes
Model-family notes
- Bosch washer drain-hose routing and filter access vary by series, but E:30 / -80 still points first to the outlet path.
- This code can overlap with more general drain faults if the pump filter is also blocked at the same time.
Display and panel differences
- Panel wording can vary by series, so confirm the exact code pattern before buying parts.
Parts, Tools and Service Options
Common parts
- Drain hose ($15–$35)
- Drain pump if motor failed ($35–$80)
Manual and model check
Check your exact model and manual before ordering any Bosch washer parts.
Service option

When Not to Keep Troubleshooting
E:30 / -80 returns after the hose path and drain connection are confirmed correct.
- The pump filter is clean but the machine still cannot drain properly.
- You suspect pump failure or a deeper blockage that is not safely accessible.
How to Prevent It Recurring
- Check drain hose routing annually — especially after moving the machine
- Clean the pump filter every 3 months
