What Does Error Code E17 Mean on a Siemens Washing Machine?
Check that the cold water tap behind the machine is fully open and the inlet hose is not kinked, then restart the cycle — if the tap was the cause, the machine should fill normally within a minute or two (takes about 5 minutes).
Fault description
Error code E17 is Siemens' way of telling you that the washing machine started a cycle but could not fill with water fast enough — or at all. The machine monitors how long it takes for water to reach the required level, and if that target is not met within a set window, it stops and displays E17 to protect the drum and motor from running dry.
When this error appears, the cycle will pause or abort entirely. You may hear the machine attempt to draw water — a faint hissing or valve click — but the drum will remain empty or only partially filled. The display will hold the E17 code until the underlying problem is resolved and the machine is reset.
The good news is that the most common causes are straightforward to check yourself without any tools. Working through the steps below in order will resolve the fault in the majority of cases.
Causes
- Water tap closed or not fully open — The cold water supply tap behind the machine must be fully open for adequate flow. Even a partially closed tap can restrict pressure enough to trigger E17.
- Kinked or crushed inlet hose — If the machine has been pushed back against the wall, the inlet hose can become bent or flattened, severely reducing water flow. This is easy to miss without pulling the machine forward to inspect.
- Blocked inlet hose filter — A small mesh filter sits inside the inlet hose connection at the back of the machine. Over time it collects sediment and limescale, gradually reducing flow until the machine can no longer fill in time.
- Low mains water pressure — Siemens washing machines require a minimum water pressure — typically around 0.5 bar — to fill correctly. Pressure drops caused by works in your area, a partially closed stopcock, or simultaneous heavy use elsewhere in the home can all trigger E17.
- Faulty water inlet valve — The inlet valve is an electrically operated solenoid that opens to let water in. If it has failed mechanically or electrically, it will not open fully or at all, preventing the machine from filling regardless of supply pressure.
- Wiring or control board fault — In less common cases, the signal from the main control board to the inlet valve may be interrupted by a damaged wire or a board fault. This is usually only suspected after all other causes have been ruled out.
Step-by-Step Fix
- 1
Check the water supply tap
Locate the cold water tap on the wall or pipe behind the machine and make sure it is turned fully anticlockwise (open). It is surprisingly common for this tap to be accidentally knocked partially closed. Once open, restart the cycle and watch to see if the machine begins to fill.
- 2
Inspect the inlet hose for kinks
Gently pull the washing machine away from the wall and run your hand along the full length of the inlet hose. Straighten out any bends or kinks you find. Push the machine back carefully, leaving a few centimetres of clearance so the hose is not compressed again.
- 3
Clean the inlet hose filter
Turn off the water tap, then unscrew the inlet hose from the back of the machine — have a towel and small bowl ready as some water will spill. You will see a small mesh filter inside the machine's inlet port. Pull it out gently with pliers, rinse it under the tap, and use an old toothbrush to remove any limescale or debris. Refit the filter, reconnect the hose, and turn the tap back on.
- 4
Check household water pressure
Turn on a cold tap elsewhere in your home and observe the flow. If pressure seems low throughout the house, check that your mains stopcock (usually under the kitchen sink) is fully open. If pressure is low across the whole property, contact your water supplier as there may be works in your area.

Reset the machine
After completing any of the checks above, reset the machine by switching it off at the power button, waiting 30 seconds, and switching it back on. Select a short cycle such as a quick wash to test whether the machine now fills correctly before running a full load.
- 6
Test the inlet valve
If the machine still will not fill after the steps above, the inlet valve itself may be at fault. With the machine unplugged and the water supply off, disconnect the inlet hose and locate the valve at the back of the machine. Check that the electrical connector to the valve is firmly seated and undamaged. If the connector looks fine but the machine still fails to fill, the valve likely needs replacing — this is a straightforward part swap but does require removing the back panel.

When to call a service technician
If you have confirmed the water supply is fully open, the hose is clear and undamaged, the filter is clean, and household pressure is normal — but the machine still displays E17 — the inlet valve has most likely failed and needs replacing. While a confident DIYer can replace this part, call a service technician if you are unsure about working with the machine's internal components or electrical connectors.
You should also contact a service technician if the E17 error returns shortly after being cleared, or if the machine shows additional error codes alongside E17. Recurring faults after a repair suggest a wiring issue or a failing control board, both of which require professional diagnosis and equipment to test safely.

Frequently Asked Questions
Can I still use my washing machine while it shows E17?
No — when E17 is active, the machine has stopped the cycle because it cannot fill with water. Running it in this state serves no purpose and will not clear the fault. Resolve the water supply issue first, then restart a cycle.
How do I reset the E17 error code on a Siemens washing machine?
Once you have fixed the underlying cause, turn the machine off using the power button and leave it for 30 seconds before switching it back on. This clears the stored error. If the fault has not been resolved, E17 will reappear as soon as the machine tries to fill again.
How long does it take a Siemens washing machine to fill with water normally?
Under normal pressure, a Siemens washing machine typically fills within two to four minutes at the start of a cycle. If it is taking noticeably longer than this — even without triggering E17 — it is worth checking the tap and filter as a precaution, since slow filling often precedes the fault.
Could a frozen pipe cause the E17 error in winter?
Yes. In very cold weather, the external section of the water supply pipe or the inlet hose itself can freeze, completely blocking water flow and triggering E17. If you suspect a frozen pipe, do not attempt to thaw it with a naked flame. Use warm towels or a hairdryer on a low setting, and ensure the area is better insulated before the next cold spell.
Is the water inlet valve expensive to replace on a Siemens washing machine?
Inlet valves are generally one of the more affordable washing machine parts, typically ranging from £15 to £40 for a genuine Siemens component depending on the model. If you are comfortable removing the back panel and disconnecting electrical connectors, it is a manageable DIY repair. A service technician call-out will add labour cost on top of the part price.
