Bosch Dishwasher Water Inlet Valve Replacement
You can replace a Bosch dishwasher inlet valve entirely from the front through the kick plate in about 20-30 minutes at an intermediate level, with no need to tip or pull the machine out. The valve fails when its solenoid coils burn out (no water) or its screen clogs with sediment (slow fill), and either triggers…
The inlet valve meters water into the tub, so a dead solenoid means no fill and a clogged inlet screen means a crawling fill. Both surface as E17 on the display. Because everything you need is reachable behind the base panel, this is one of the more approachable Bosch repairs.
Before you start#
| Category | What you need |
|---|---|
| Tools | Torx T20 driver, Torx T15 driver, 10mm wrench, needle-nose pliers, multimeter, bucket, towels |
| Parts | Water inlet valve (verify the BSH part number for your model) |
| Time and level | 20-30 minutes, Intermediate |
Safety warning: Disconnect power at the circuit breaker and close the water supply valve under the sink. Have a bucket positioned before disconnecting the supply line — residual water is under pressure and will spray if released without a catch basin.
Do You Have the Right Tools?
Water pressure gauge ($60), spray arm tester, float switch multimeter ($85), and drain inspection camera. Our technician arrives with $3,000+ in professional tools — your diagnostic is free.

Diagnose first: clean or replace?#
| Symptom | Likely cause | Fix |
|---|---|---|
| No water, no buzz from valve | Dead solenoid coil | Replace valve |
| Buzzing but very slow fill | Clogged inlet screen | Clean screen only |
| Fills continuously, will not stop | Solenoid stuck open | Replace valve |
| Fills only sometimes | Partly clogged screen or tired solenoid | Clean; replace if it persists |
Step-by-step#
1 - Kill power and water. Switch off the dishwasher breaker, close the hot-water supply valve under the sink clockwise until firm, and open the door to confirm the panel is dark.
2 - Remove the kick plate. Take out the two Torx T20 screws near the bottom corners, slide the panel forward about a quarter inch, then lift it away. You now see the base: the inlet valve at lower-left, the drain pump center-left, and the supply line entering from below.
3 - Disconnect the supply line. Set the bucket beneath the connection and loosen the brass nut with the 10mm wrench; let the line drain as the seal breaks, then remove the nut and pull the line off. Inspect the rubber washer in the nut and replace it if flat or cracked.
4 - Unplug the valve. Press the release tab on the 2-pin or 4-pin connector and pull it straight off, photographing which lead serves which coil if there are two.
5 - Free the internal fill hose. Squeeze the ears of the spring clamp with pliers, slide it back, and work the hose off the outlet barb over a towel, since a little water drains out.
6 - Release the valve. Undo the 1-2 Torx T15 bracket screws or press the snap-clip tab, then pull the valve out through the kick-plate opening, noting its exact orientation.
7 - Transfer the inlet screen. If the new valve lacks a mesh screen, pry the old one from the inlet port and press it into the replacement. Without that screen, sediment reaches the solenoid and shortens its life.
8 - Install the new valve. Set it in the original orientation, secure the Torx T15 screws or clip, push the fill hose fully onto the outlet barb and slide the clamp over it, then click the electrical connectors home.
9 - Reconnect the water. Start the brass nut by hand to avoid cross-threading, then tighten it hand-tight plus a quarter turn with the 10mm wrench. The nut seals on the rubber washer, so over-tightening ruins both.
10 - Test for leaks. Open the supply valve slowly, a quarter turn at a time, and watch the brass nut and fill-hose joints. Dry after 30 seconds at full pressure, restore power and run a Quick Wash, watching through the opening for five minutes, then refit the kick plate and its two Torx T20 screws.
Safety First — Know the Risks
Live 120V wiring in a wet environment is one of the most dangerous DIY scenarios. Water + electricity = serious shock risk. Our techs are licensed and insured — let them handle the risk.

When to call a professional#
EasyBear technicians serving Sacramento and the Bay Area carry Bosch-specific diagnostic tools and replacement parts on every service call.
- The brass supply fitting on the dishwasher body is stripped or cross-threaded.
- The AquaStop system has tripped (E15) alongside the fill failure and the base pan needs draining.
- The valve gets no voltage despite good coils, which means board-level diagnosis.
