Bosch Washing Machine Error E17 – Causes & Fix
The washer couldn't fill to level in time – usually a closed valve, a kinked hose or a clogged inlet screen.

E:17 (F17 on older Bosch washers) means the water level in the tub didn't rise to target within the time the control allows for filling. Bosch's 24-inch compact washers sold in the US connect to both hot and cold water and need 14.5–145 psi with at least about 2.2 gallons per minute of flow. A supply valve left half-closed, a hose crushed when the washer was pushed into a closet, or inlet screens packed with sediment are the usual reasons. On models with the AquaShield hose, a tripped internal valve blocks the flow completely. Many models first flash the faucet symbol and only show E:17 if the supply problem continues.
How it looks on the display
Model families & display variants
| Model family | Shows | Note |
|---|---|---|
| Current 24-inch 300/500/800 Series compacts | E:17 | Often preceded by a flashing faucet symbol. |
| Older Axxis and Nexxt washers | F17 | Same water-supply fault with the F prefix. |
| Models with AquaShield hoses | E:17 | A red indicator window at the faucet end means the hose blocked the flow and must be replaced. |
Safety first · Consult a professional
Supply hoses are under full house pressure. Close both valves and unplug the washer before unscrewing a hose, and keep a towel ready for the water trapped inside.
- Water and electricity: unplug first, keep towels ready and never stand in water while the appliance is connected.
Symptoms
- Faucet symbol flashes, then E:17 appears
- Little or no sound of water entering the drum
- Cycle stalls at the start with a dry or barely damp load
- Detergent stays in the dispenser drawer
- Code appears after plumbing work or a water heater flush
Possible causes
Ranked by how often each cause is behind this code (editorial estimate).
- Hot or cold supply valve closed or only partly open
- Inlet screens clogged with sediment or scale
- Supply hose kinked in a closet or stacked install
- AquaShield hose safety valve tripped (red indicator)
- Low house pressure, e.g. well pump or failing pressure regulator
- Water inlet valve in the washer failed
- Pressure sensor or control fault
Fix it step by step
Check both supplies
Open a nearby faucet on hot and cold. If one side is weak or off, the problem is in the house plumbing, not the washer. Then make sure both washer valves are fully open.
Tools: Flashlight
Relieve pressure, then remove the hoses
Close both valves, start any wash cycle for about 40 seconds to bleed the pressure, switch off and unplug. Unscrew the hoses at the washer with a towel underneath.
Tools: Towels & shallow pan
Clean the inlet screens
Rinse the screen at the faucet end of each hose, then pull the screens out of the inlet ports on the washer's back with needle-nose pliers. Brush off grit and scale under running water and push them back in.
Tools: Pliers, Soft brush
Flow test into a bucket
With the hose end in a bucket, open the valve fully. The minimum Bosch asks for fills a one-gallon container in under about 30 seconds, and a healthy supply is much quicker; a trickle points to a clogged valve, a bad hose or low house pressure.
Tools: Towels & shallow pan
Replace a tripped AquaShield hose
A red indicator means the internal valve has closed for good. Order a replacement hose through Bosch service and fit it hand-tight plus a quarter turn.
Suspect the inlet valve last
If both supplies run strong, screens are clean and the washer still hums without filling, the inlet valve or its wiring has likely failed and needs a technician.
Tools: Multimeter, Screwdriver
How to reset E17
- Turn the cycle selector to Off.
- Fix the supply problem and reopen both valves.
- Turn the washer back on and start the cycle again – the code clears once water flows normally.
- If E:17 returns straight away, unplug for a minute and recheck screens and hoses before calling service.

Rough US estimates; technician call-out fees vary by region. Not a quote.
When to call a technician
Call Bosch service or an appliance tech when water flows strongly into a bucket from both hoses, screens are clean, and E:17 still appears. If a faucet elsewhere in the house is weak too, a plumber should check the pressure regulator or well system first.
Frequently asked questions
Does my Bosch need both hot and cold connected?
The US compact washers are designed for both hookups, and the manual tells you to connect both. Leaving the hot side capped or closed can trigger a water-supply message.
What is the AquaShield hose?
It's a double-walled supply hose with a mechanical safety valve. If the inner hose leaks, the valve shuts, the indicator turns red and no more water reaches the washer until the hose is replaced.
Why did E:17 start right after we flushed the water heater?
Flushing stirs up sediment that the hot-side inlet screen catches. Cleaning that screen usually fixes it within minutes.
