BOSCH E:30 / -10

Bosch Washing Machine Error E:30 / -10: Water Intake Issue — Multiple Possible Causes

Clear meaning, realistic next steps, and safe guidance without turning the page into a long repair manual.

What it means

The washing machine cannot fill with water properly. Multiple causes are possible — the display may also show a faucet icon alongside this code.

Severity

Medium - some user checks may help, but repeated faults often need service.

Can you fix it yourself?

Partial — start with DIY steps

Most likely cause

Water pressure too low at the household supply

Estimated time for safe first checks: 15–30 min.

Step-by-Step DIY Fix Guide

  1. SAFETY: Turn off the water tap before touching the inlet hose.
  2. Check that the water supply tap is fully open.
  3. Inspect the inlet hose for kinks behind the machine.
  4. Remove and clean the mesh filter inside the inlet hose connector.
  5. If water pressure at the tap is genuinely low, contact your plumber — a pressure issue cannot be fixed on the machine.
  6. If tap, hose, and filter are all fine but E30-10 remains, the water level sensor needs professional diagnosis.

If it's still not filling correctly

  • If normal household water flow looks good but the code returns, the inlet-valve or fill-sensing path becomes more likely.
  • If airflow still seems weak after the basic checks, the fan path or a deeper obstruction becomes more likely.
  • If the warning returns immediately after a clean restart, the sensor or wiring path becomes more likely than a one-time glitch.

What This Error Means

E:30 / -10 on your Bosch washing machine means: The washing machine cannot fill with water properly. Multiple causes are possible — the display may also show a faucet icon alongside this code. The machine detects this condition via its sensors and stops the current cycle to prevent further damage. The error will remain until the underlying cause is resolved.

The most frequent cause is water pressure too low at the household supply. Work through the causes listed below in order — the first cause is the most likely and the most straightforward to check.

Many cases of E:30 / -10 can be resolved with DIY troubleshooting. Follow the steps below — if the error persists after all steps, a technician will be needed. The guide below specifies clearly at which point to escalate.

The drum will remain empty or partially filled, and the wash cycle will not progress. Turn off the water tap before inspecting the inlet hose or filters.

Most Likely Cause by Symptom

The Bosch washing machine may stop, pause, or refuse to complete the cycle normally.

Likely cause: Water pressure too low at the household supply

Check first: SAFETY: Turn off the water tap before touching the inlet hose.

Performance may drop because airflow, filtering, or draining is restricted.

Likely cause: Mesh filters in water inlet hose blocked with sediment

Check first: Check that the water supply tap is fully open.

The warning may return immediately because the appliance is detecting an internal fault.

Likely cause: Water supply tap closed or only partially open

Check first: Inspect the inlet hose for kinks behind the machine.

Common Causes

  • Water pressure too low at the household supply
  • Mesh filters in water inlet hose blocked with sediment
  • Water supply tap closed or only partially open
  • Water inlet hose kinked or jammed
  • Water level measurement system (pressure switch) defective

What Not to Do

  • Do not run repeated cycles without water — heating element will burn out
