E19
Bosch Washing Machine
Severity: CriticalWhat Does This Error Mean?
The E19 error means the water inside your Bosch washing machine is overheating. The temperature has gone above the set programme level. The machine stops automatically to protect your clothes and the drum seal.
Affected Models
- WAW285H2GB
- WAN28080GB
- WAT28400GB
- Most Bosch front-load washing machines
Common Causes
- The heating element thermostat has failed and is not cutting power to the heater
- The NTC temperature sensor has failed and is reporting the wrong temperature
- Hot water is being supplied directly instead of cold — bypassing the heater control
- The control board is not correctly limiting heating based on the programme setting
- A limescale-coated heater is creating hotspots beyond the set temperature
How to Fix It
-
Turn off the programme dial immediately and unplug the machine.
Do not open the door if the machine has been running hot — hot water may pour out.
-
Wait at least 30 minutes for the machine and water to cool.
Only open the door when the machine has fully cooled down.
-
Check whether the machine is connected to a hot water supply.
Bosch washers are designed for cold water supply only. If connected to a hot feed, the heater control can't compensate — this causes overheating.
-
Unplug for 15 minutes and then plug back in.
A power reset can clear a temporary NTC sensor misread.
-
If E19 returns on the next cycle, stop using the machine and call a technician.
A failed thermostat or NTC needs replacement before the machine is safe to use.
When to Call a Professional
E19 is a serious error — overheated water can damage your clothes and drum seal. Do not restart the machine until the cause is identified. Heating element thermostat or NTC replacement: $100–$300 including labor. If the control board is at fault, expect $200–$400.
Frequently Asked Questions
Can E19 damage my clothes?
Yes. Temperatures well above the set programme can shrink delicate fabrics, damage colours, and ruin synthetics. The machine stops automatically to limit damage — but always check your clothes after an E19 event.
Why would my Bosch washer suddenly overheat?
The most common reasons are a failed heating thermostat or a faulty NTC sensor. These are normal wear parts that can fail after 5–10 years. A gradual limescale buildup on the heater can also create uneven hotspots that trigger E19.
Is it safe to use the washer on a cold cycle while waiting for repairs?
Cold cycles (30°C or lower) don't engage the heating element — so they are generally safe. Avoid any programme above 30°C until the heater thermostat or NTC is repaired.
