Bosch E17 is an overfill - the inlet valve is not closing fully and water is seeping in when it should stop. Fix fast: E17 left alone escalates to E15 (flood protection). First check your water pressure (needs to be under 87 PSI - high pressure forces past the valve). Then test the solenoid: disconnect the 2-wire connector and measure resistance, should read 500-1,500 ohms. Open circuit means the solenoid is burned out.
Look, E17 is your dishwasher saying it's getting way too much water. The inlet valve isn't shutting all the way, and water keeps trickling in when it should've stopped already. Here's why you don't want to ignore this: that extra water eventually slops over into the base pan and triggers E15, which is full flood protection mode. That's a way bigger headache. Fix the valve first and you'll avoid the whole cascade.
OK so E17 is actually pretty common on Bosch dishwashers, especially ones that are 5-7 years old. I probably see three or four of these a month. The inlet valve wears out, the rubber diaphragm gets stiff or cracks, and water just keeps seeping in past it when it shouldn't. Sometimes it's not even the valve's fault. It's your house water pressure being too high and literally forcing water through. Good news is the valve part is usually under $40 and it's not a hard swap.
Most Likely Causes
Based on aggregated repair data, here is the probability breakdown for this error code:
Water inlet valve diaphragm worn, allowing water to seep past when closed40%
Excessively high home water pressure forcing past the valve24%
Cracked or deteriorated inlet valve body22%
Failed flow meter not accurately counting water volume14%
Symptoms You May Notice
E17 flashes on the display right during the fill phase, before the wash cycle even gets going.
You open the door after a failed start and there's way more water in the bottom than there should be, like it's almost up to the heating element.
E15 shows up a day or two after you've been ignoring E17, which means water already made it into the base pan and tripped the float switch.
Water actually dripping from the front of the dishwasher onto the floor during filling, even with the door closed tight.
Cycle starts, fills way longer than normal, then errors out instead of moving on to the wash phase.
Can you reset a Bosch dishwasher to clear the E17 code?
After you've fixed the valve or pressure issue, hold the Start/Reset button for 5 seconds. The dishwasher will kick into a short drain cycle to clear out any excess water, takes about 90 seconds. Once it stops and goes quiet, you'll either see a clear display or it'll go back to the start screen. If E17 comes back on the next fill cycle, the valve or flow meter fix didn't fully take and you'll need to dig deeper.

Frequently Asked Questions
Can high water pressure cause E17 without a bad valve?
Absolutely yes, and honestly this is more common than people think. Bosch's hard maximum is 87 PSI. A lot of homes, especially on municipal supply, run 90-110 PSI with no pressure reducing valve installed. At that pressure, water just forces its way past the valve diaphragm whether the solenoid is closed or not. Grab a $10 gauge from the hardware store and check it before you buy any parts. If you're over 87, a $30-50 pressure reducing valve on the supply line will fix your E17 without touching the dishwasher at all.
Where is the water inlet valve on a Bosch dishwasher?
It's at the bottom of the dishwasher where the hot water supply hose connects. Pull off the lower front kick panel (usually two screws) and look toward the left side near the water connection. You'll see a valve body with one hose coming in from your supply, one hose going into the dishwasher, and one or two wire connectors plugged into the solenoid. Hard to miss once you're looking at it. Takes maybe 5 minutes to get to it.
Is E17 directly related to E15?
Yeah, it's basically cause and effect. E17 means too much water is coming into the tub. If you don't stop it, that water eventually spills over the tub base and drips down into the bottom drip pan. When the float switch sitting in that drip pan gets wet, it trips E15, which is full flood protection mode and the dishwasher won't run at all until you dry out that pan. Catching E17 early is way easier than dealing with E15. Don't run the machine again until E17 is fixed.
Can I use the dishwasher with E17 active?
No. Seriously, don't. The dishwasher is actively pulling in more water than it's supposed to, and it's just a matter of time before that water gets into the base pan and you're dealing with E15 and potential floor damage. I've seen people run it a couple more times thinking it'll clear itself and then they've got water under the laminate flooring. Turn the supply off under the sink right now and don't run it again until the valve or pressure issue is sorted out.
What is a flow meter and how does it cause E17?
The flow meter is basically a small water counter on the inlet line. There's a tiny turbine wheel inside that spins as water flows past it, and the control board counts those spins to know how many liters came in. When it hits the target, it closes the valve. If that turbine gets stuck from mineral deposits (super common in hard water areas) the board never gets an accurate count, so it just keeps the valve open and keeps filling. Replacement part usually runs $15-30. I replaced one last week on a SHPM88Z75N and it fixed it right away.
How much does it cost to fix a Bosch E17?
If it's just the water inlet valve, the part runs about $25-45 depending on your model. Takes 30-45 minutes to replace if you've never done it before. If a tech does it, you're probably looking at $150-250 total with labor. If the fix is a pressure reducing valve on your supply line, that's $30-60 for the part. Flow meter is $15-30 and takes about 20 minutes. Honestly it's one of the cheaper dishwasher repairs out there, and way cheaper than the floor damage you'd get from ignoring it.
