Bosch E19 Error: Water Fill Valve Malfunction

Quick Answer

Bosch E19 means the fill valve solenoid is not opening or closing when the control board signals it. Test with a multimeter: disconnect the 2-wire connector at the inlet valve and measure resistance - 500 to 1,500 ohms is good, open circuit means the solenoid coil burned out. If the solenoid tests fine but E19 appears intermittently, you have a sticking plunger - it works cold but jams when the valve warms up.

Bosch E19 points to a problem with the water fill valve actuation - the valve solenoid is not opening or closing correctly when the control board sends a signal. This is distinct from 5UC (no water supply) and E07 (no flow detected). Test the fill valve solenoid with a multimeter: it should read 500-1,500 ohms. An open circuit indicates a burned-out solenoid coil. E19 can also appear intermittently from a sticking solenoid, which may work on cold starts but fail when warm.

What Does the E19 Code Mean?

The water inlet valve on a Bosch dishwasher has one or two solenoid coils that open and close the valve when energized by the control board. E19 indicates the control board detected an issue with this solenoid circuit - either no current response (solenoid failed), unexpected current draw, or the diverter valve (present on some models to direct water to different spray zones) is not responding.

Most Likely Causes

Based on aggregated repair data, here is the probability breakdown for this error code:

Fill valve solenoid coil burned out (open circuit)40%
Diverter valve solenoid failure on multi-zone models24%
Wiring damage between control board and inlet valve22%
Sticking solenoid plunger causing intermittent E1914%

Symptoms You May Notice

  • E19 displayed during fill phase
  • Dishwasher not filling with water before E19 appears
  • Intermittent E19 that clears with a cool-down period
  • E19 on hot cycles but not cold start cycles

Can you reset a Bosch dishwasher to clear the E19 code?

After replacing the inlet valve, hold Start/Reset for 5 seconds and run a test fill cycle to confirm E19 is cleared.

Diagnostic Checklist

Follow these steps in order. We start with the easiest external fixes before opening up the machine.

1

Test the inlet valve solenoid resistance

Turn off power at the circuit breaker and shut off the water supply valve under the sink. Locate the inlet valve at the back lower area of the dishwasher where the supply hose connects. You may need to pull the unit forward slightly to access the rear. Disconnect the solenoid's 2-wire connector. Set the multimeter to resistance (ohms). Place the probes on the two solenoid terminals. The expected resistance range is 500 to 1,500 ohms for a functional solenoid. An open circuit reading (OL or infinite) confirms the solenoid coil wire has burned through internally. A very low reading (below 100 ohms) indicates a shorted coil. Either condition requires replacing the inlet valve assembly.

2

Check for intermittent solenoid sticking

3

Test the diverter valve if equipped

4

Check inlet valve wiring harness

Replacement Parts

If your diagnostic testing proves the component has failed, you will need a replacement. We recommend OEM parts over aftermarket for water-handling components.

Frequently Asked Questions

What is the difference between E19 and 5UC on a Bosch dishwasher?
5UC means no water supply was detected at all - the dishwasher opened the valve but found nothing coming through. The cause is almost always external to the dishwasher (shut-off valve closed, AquaStop hose triggered, kinked hose). E19 means the fill valve solenoid circuit itself has an electrical fault - the control board sent a signal to open the valve but detected an abnormal response from the solenoid circuit. E19 is an internal component failure; 5UC is a supply path problem. If you have E19 and the water supply is confirmed on, the valve solenoid is the next item to test.
How do I test the fill valve solenoid on a Bosch dishwasher?
Turn off power and water. Locate the inlet valve at the rear of the dishwasher. Disconnect the solenoid's 2-wire connector. Set a multimeter to resistance mode (ohms). Place the probes on the two solenoid terminals and read the resistance. A reading of 500-1,500 ohms indicates a functional coil. An OL (open loop) reading means the coil wire has burned through internally and the valve must be replaced. A reading below 100 ohms indicates a short circuit - also requires replacement.
Why does E19 only show up sometimes on my Bosch?
Intermittent E19 most commonly indicates a solenoid plunger that sticks due to mineral deposits. When the solenoid is cold, the plunger moves freely and the valve opens normally. After several cycles of hot water flow, the plunger shaft heats up and thermal expansion causes stiction against the mineral deposits - the solenoid then fails to open fully. This pattern shows as E19 appearing after the dishwasher has been running a while but not on the first cycle of the day. Replacing the inlet valve is the correct fix for this condition.
Where is the diverter valve on a Bosch dishwasher?
The diverter valve on Bosch dishwashers is typically mounted on or adjacent to the circulation pump housing at the bottom center of the dishwasher tub. It is accessed by removing the lower spray arm and the bottom filter assembly, then removing the pump cover. Not all Bosch models have a diverter valve - it is more common on 500 and 800 series models with multi-zone wash systems. The diverter valve has its own solenoid with a separate wiring connector from the main inlet valve.
Can E19 appear after plumbing work in the kitchen?
Yes. Plumbing work that disturbs water supply pipes can send pipe scale or solder fragments downstream into the dishwasher supply line. These particles can lodge in the solenoid valve body and cause the plunger to stick in the closed position, producing E19 symptoms. If E19 appears within days of plumbing work in the kitchen, disconnect the supply hose, remove the inlet valve, and inspect for debris inside the valve body. Replacing the inlet valve is appropriate if debris has entered the valve housing.
