The E19 error on your Bosch Dishwasher means the appliance has detected a water inlet or water heating fault, usually linked to poor water flow into the unit or a heating element that isn't reaching temperature within the expected time. This often points to a blocked inlet valve, low water pressure, or a failing heating circuit. Restarting the cycle after checking the water supply resolves it in many cases.
| Error code | E19 |
|---|---|
| Meaning | Water inlet or heating system fault detected during a wash cycle |
| Severity | Medium — the dishwasher may still run but with incomplete washing or heating results |
| Time to fix | 15–45 minutes |
| Tools needed | Adjustable pliers, multimeter (optional), towel for spills |
What the E19 error means
The E19 code appears when the dishwasher's control board detects that water isn't entering the machine fast enough, or that the water heating element isn't warming the water within its programmed time window. Bosch dishwashers rely on consistent water pressure and a functioning heater to complete wash and rinse cycles properly. When either of these systems underperforms, the control board halts the cycle and flags E19 as a safety measure to avoid running an empty or under-heated wash.
Common causes
- Kinked, blocked, or partially closed water supply hose
- Low household water pressure feeding the dishwasher
- Clogged inlet valve filter screen collecting mineral deposits or debris
- Faulty water inlet valve that won't open fully
- Failing heating element or thermostat that can't reach set temperature
- Loose or damaged wiring connection to the heater or inlet valve
How to fix the E19 error
- Check the water supply valve — Make sure the shutoff valve under the sink or behind the dishwasher is fully open, not partially closed.
- Inspect the inlet hose — Straighten any kinks or bends in the water supply line that could restrict flow.
- Clean the inlet filter screen — Disconnect the water hose at the dishwasher connection and clean any mineral buildup or debris from the small mesh filter inside.
- Test water pressure — Run a kitchen tap on cold to confirm normal household water pressure; low pressure elsewhere in the home can also affect the dishwasher.
- Reset the dishwasher — Turn off power at the breaker for two minutes, then restart and run a short cycle to see if the code clears.
- Call a technician for the heating element — If the error persists after checking water flow, the heating element or thermostat likely needs professional testing and possible replacement.
FAQ
Can I keep using the dishwasher with an E19 error showing?
It's best not to. Running cycles with a water flow or heating fault can leave dishes poorly cleaned or cause further strain on internal components.
Will turning the dishwasher off and on clear the E19 code?
Sometimes, yes. A power reset clears temporary faults, but if the underlying water flow or heating issue remains, the code will return on the next cycle.
Is E19 expensive to repair?
If it's just a blocked filter or hose, the fix is free. If the heating element or inlet valve needs replacing, expect a moderate parts and labour cost from a qualified appliance technician.
