E02
Bosch Washing Machine
Severity: ModerateWhat Does This Error Mean?
The E02 error on your Bosch washer means it took too long to fill with water. The machine expected water to reach a certain level within a set time. It gave up waiting and stopped the cycle.
Affected Models
- Bosch 300 Series
- Bosch 500 Series
- Bosch 800 Series
- Most Bosch front-load washers
Common Causes
- The hot or cold water supply valves behind the washer are not fully open
- The water inlet hoses are kinked or bent, restricting flow
- The inlet valve screens are clogged with sediment or debris
- The water inlet valve itself is faulty and not opening properly
- Low water pressure in your home's plumbing system
How to Fix It
-
Check that both hot and cold water supply valves behind the washer are fully open. Turn them counterclockwise to open.
These valves sometimes get bumped closed when moving the washer.
-
Inspect the water inlet hoses for any kinks, bends, or damage. Straighten them out if needed.
Replace any hoses that are cracked or bulging.
-
Turn off the water supply and disconnect the hoses from the back of the washer. Clean the small mesh screens in the inlet ports.
Use an old toothbrush to remove sediment. These screens clog over time and slow water flow.
-
Check your home's water pressure by running another faucet. If pressure is low everywhere, the issue is your plumbing, not the washer.
Normal household water pressure is 40–60 PSI.
-
If the screens are clean and pressure is fine, the water inlet valve may be faulty and needs replacement.
This part costs $40–$90. A technician can install it in about an hour.
When to Call a Professional
If you have checked the supply valves, hoses, and screens and the error still appears, the water inlet valve likely needs replacing. A qualified technician can test it and swap it out. Expect repair costs of $120–$280 including parts and labor.
Frequently Asked Questions
Can I still use my Bosch washer with the E02 error?
No — the washer cannot run a cycle without enough water. You need to fix the water supply issue first. Once water flows normally, the error should clear on its own.
What are the mesh screens and where do I find them?
They are small filters inside the water inlet ports on the back of the washer. Where the hoses connect, you will see tiny metal screens. They catch sediment from your water supply. Over time they get clogged and restrict water flow.
Could low water pressure cause the E02 error?
Yes — if your home has low water pressure, the washer may not fill fast enough. Try running a kitchen faucet at the same time. If the flow is weak there too, contact your water utility. A plumber can also check if your pressure regulator needs adjusting.
