Bosch SHS863WD5N 24 in 300 Series Top Control 46 dBA E13 Error Fix: Water Heating Timeout

Error code E13 on the Bosch SHS863WD5N 24 in 300 Series Top Control 46 dBA means: Water Heating Timeout. The water did not reach the target temperature within the allowed heating time. This differs from E1 (no heating at all) — E13 means the heater is working but too slowly. Common causes: very cold incoming water supply, a partially failed heating element with reduced output, or a defective temperature sensor giving incorrect readings. Check the hot water supply temperature at the kitchen faucet — it should be at least 120°F for best performance. Inspect the heating element for scale buildup reducing efficiency.
