What this error means
The E17 error code on your Bosch washing machine means the machine has not filled with enough water within the expected time — usually caused by a problem with the water supply, inlet hose, or inlet valve.
The E17 error is a water fill timeout fault. Your Bosch washing machine expects to fill to the correct level within a set time at the start of a cycle. If it cannot achieve this, it stops and displays E17 rather than attempting to run a dry drum, which could damage the heating element and motor. The most common causes are a closed or partially closed water supply tap, a kinked or blocked inlet hose, a clogged inlet filter mesh (a small screen inside the water connection at the back of the machine), low water pressure from the mains supply, or a faulty water inlet valve solenoid that is not opening fully. In most cases this is a simple fix you can carry out in minutes.

Step-by-step
Symptoms to look for
- Machine pauses at the start of a cycle and will not fill
- E17 displayed on the control panel
- Drum sounds dry when the cycle should have started
- Cycle takes much longer than usual to begin
- Machine fills very slowly and eventually stops
Diagnostic steps
Go behind the machine and check that the isolation tap is fully open (turned anticlockwise as far as it will go). Then go to another tap in the house — a kitchen sink or bathroom basin — and run the cold water to check the pressure feels normal. If pressure is low or water is off, contact your water provider.
Turn the machine off and remove the plug from the socket. Pull the machine forward to give yourself access to the back.
Check the entire length of the cold water inlet hose for kinks, tight bends, or crush damage — particularly where it passes behind the machine. Kinks can significantly restrict flow even if the tap is fully open. Straighten any kinks and make sure there is a gentle curve rather than a sharp bend.
Turn off the water supply tap. Place a towel under the inlet connection at the back of the machine, then unscrew the inlet hose by turning it anticlockwise. Some water will trickle out — this is normal. Look into the threaded inlet connection on the back of the machine — you will see a small plastic or metal mesh filter screen. Grip it with a pair of pliers and pull it straight out. Rinse it under a running tap and use an old toothbrush to remove any limescale or grit. Refit it carefully, making sure it is pushed in straight.
Screw the inlet hose back onto the machine by hand. Once hand-tight, give it a further quarter turn with a spanner — but do not overtighten as you can crack the plastic fitting. Slowly turn the water supply tap back on and check the connection for drips before moving to the next step.
If the above steps do not resolve E17, the water inlet valve solenoid (the electrical valve inside the machine that controls water flow) may be faulty. You can test this by listening at the back of the machine at the start of a fill cycle — you should hear a faint click as the valve opens. No click, or a click with no water flow despite good mains pressure, points to a faulty valve. Inlet valve replacement is a moderately straightforward repair for a confident DIYer or can be carried out by an engineer.
When to call an engineer
- E17 persists after checking tap, hose, and filter mesh
- Inlet valve clicks but water does not flow despite normal mains pressure
- Inlet valve does not click at the start of a cycle
- Suspected wiring fault on the inlet valve
- Low mains pressure confirmed — engineer can fit a booster or advise on alternative solutions
