When to Call a Professional
Call a professional plumber or appliance technician if the water heater temperature adjustment doesn't resolve the issue, if you're uncomfortable working with gas water heaters, or if the temperature sensor or water inlet valve needs replacement. Also seek professional help if you suspect internal dishwasher components are damaged.Frequently Asked Questions
What temperature should my water heater be set to for a Bosch dishwasher?
Your water heater should be set between 120°F and 140°F for optimal dishwasher performance. This provides effective cleaning while preventing the E13 error code.
Can I run my Bosch dishwasher with the E13 error showing?
No, you should not run the dishwasher when the E13 error is displayed. This error prevents operation to protect the appliance and your dishes from damage caused by excessively hot water.
How do I reset my Bosch dishwasher after fixing the E13 error?
Unplug the dishwasher for 5 minutes, then plug it back in. The error code should clear automatically if the hot water temperature issue has been resolved.
Why does my Bosch dishwasher suddenly show E13 when it worked fine before?
The E13 error can appear suddenly if someone recently adjusted your water heater temperature, if the temperature sensor is beginning to fail, or if there's an issue with the water inlet valve.
Is the E13 error code covered under Bosch warranty?
If the E13 error is caused by a faulty temperature sensor or water inlet valve, it may be covered under warranty. However, if it's due to improper water heater settings, this is considered a user/installation issue and typically isn't covered.
