Bosch Dishwasher Error Code E08 — Low Water Level in Circulation System
What this means
The E08 error indicates that the circulation system does not have enough water to operate properly. This can occur if the water inlet valve is not opening fully, the water supply pressure is too low, or there is a leak in the internal plumbing causing water loss before it reaches the pump.
Alternate codes: E8
Step-by-step fix
3 stepsCheck the water supply
Verify the water supply valve under the sink is fully open and that no other appliance is using water simultaneously.
Low household water pressure is a common cause, especially in homes with well water systems.
Inspect the inlet hose
Check the water inlet hose for kinks, blockages, or a clogged filter screen at the connection point.
The small mesh filter screen at the inlet valve can accumulate mineral deposits over time.
Check for internal leaks
Run a short cycle and look under the dishwasher for drips. Check hose clamps on the internal water lines.
Even a small leak can reduce water level enough to trigger this error.
When to call a professional
If the water supply is fine and no leaks are found, the water inlet valve may need replacement, which can be done by a qualified technician.
