Bosch Dishwasher Not Filling with Water: Full Walkthrough

Quick Answer

A Bosch dishwasher not filling with water has five possible causes in order of likelihood: water supply valve closed under the sink, AquaStop hose triggered into lockout mode, kinked supply hose, clogged inlet valve screen, or a failed inlet valve solenoid. The fix takes 5 minutes if it is the supply valve, up to $60 if the AquaStop hose needs replacement, or up to $60 for a new inlet valve.

SYMPTOM

What Does the SYMPTOM Code Mean?

Water must pass through five points to reach the dishwasher tub: the household water supply, the shut-off valve under the sink, the supply hose, the AquaStop hose connector, the inlet valve screen, and the inlet valve solenoid. Any one of these can prevent water from reaching the tub. Bosch dishwashers may show 5UC, E07, or E05 error codes during a no-water condition, or may show no code at all if the issue is caught immediately at startup.

Most Likely Causes

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

Water supply shut-off valve closed or partially closed40%

AquaStop hose flood prevention lockout triggered24%

Supply hose kinked or pinched14%

Inlet valve solenoid coil failed (not opening when energized)12%

Inlet valve mesh screen completely clogged with mineral sediment10%

Symptoms You May Notice

Dishwasher starts but no fill sound in first 30 seconds
5UC, E07, or E05 displayed on panel
Dry tub after cycle completes with no cleaning
Dishwasher stops and beeps after 30-60 seconds without water

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

After opening the supply valve, replacing the AquaStop hose, or replacing the inlet valve, hold Start/Reset for 5 seconds and run a test cycle.

Diagnostic Checklist

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

Check the water supply valve

Open the cabinet under the kitchen sink. Find the hot water supply valve for the dishwasher - it is a separate valve from the main sink supply, typically a ball valve with a lever handle or a gate valve with a round handle tapped into the hot water supply pipe. If it is a ball valve, the lever should be parallel to the pipe for fully open and perpendicular for closed. If it is a gate valve, turn it counterclockwise fully. Partial opening of a gate valve is a common cause of no-water or slow-fill issues because gate valves can appear open while actually only 20-30% open internally. Fully open the valve and run a test cycle to confirm.

Check the AquaStop hose

Inspect the supply hose for kinks

Clean the inlet valve screen and test the solenoid

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

How do I check if the AquaStop hose has triggered on my Bosch dishwasher?

Disconnect the AquaStop hose at the inlet valve end of the dishwasher (have a towel ready for residual water). Hold the hose fitting that connects to the dishwasher inlet and blow firmly into it with your mouth. A functional AquaStop hose allows air to pass through with light to moderate resistance. If you cannot push any air through the fitting regardless of how hard you blow, the internal float has triggered its lockout position and is blocking all flow. The hose cannot be reset - it requires replacement. Order the OEM Bosch AquaStop hose specific to your model.

How do I clean the inlet screen on a Bosch dishwasher step by step?

Turn off the water supply valve under the sink and disconnect power at the circuit breaker. Pull the dishwasher forward to access the back. Disconnect the supply hose from the inlet valve body - have a towel ready for water drips. Look into the inlet valve port - the mesh screen is a small cylindrical strainer about 15-20mm in diameter. Use needle-nose pliers to grip the outer rim of the screen and pull it straight out. Rinse under running water. For scale buildup, soak in undiluted white vinegar for 15-30 minutes, then rinse thoroughly. Press the clean screen back into the port, reconnect the hose and power, and run a test cycle.

Why is there no water and no error code on my Bosch dishwasher?

No water and no error code suggests the dishwasher stopped before it even attempted to fill - meaning the control board did not get to the point of opening the inlet valve. This happens when a door latch fault prevents the cycle from starting, or when there is an immediate power issue. Check that the door is fully latched with a clear click. Check that the Start button was pressed (on front-control models) or that the door was closed to initiate the cycle (on hidden-control models). If the unit powers on but shows no active cycle, confirm Child Lock is not active.

What are the water pressure requirements for a Bosch dishwasher?

Bosch requires a minimum dynamic water pressure of 15 PSI at the inlet valve and a maximum of 87 PSI. Static pressure in most US homes is 40-80 PSI, which is well within range. Low-pressure areas (well systems, end-of-long-pipe runs) can be at or below the 15 PSI minimum, especially during peak demand hours. If you suspect low pressure, purchase an inexpensive water pressure gauge, attach it to the supply valve under the sink, and take a reading. A reading consistently below 20 PSI will cause intermittent fill problems.

Can the AquaStop hose lockout be reset without replacing it?

No. The AquaStop lockout mechanism is intentionally permanent and irreversible. When the internal float triggers, it mechanically blocks the hose fitting in a way that cannot be undone from outside the hose. The design philosophy is that a triggered AquaStop means a real leak was detected, and continuing to use the hose risks flooding your kitchen. Attempting to disassemble the fitting to reset it voids the flood protection and typically destroys the fitting. Replace it with an OEM Bosch AquaStop hose - third-party standard hoses lack the flood protection and are not equivalent replacements.
