Bosch washers are quiet, compact and precise — and when something goes wrong they say so with E-codes on the display, the same language their dishwashers speak in our Bosch E15 & E24 guide. Each code names a symptom, not an invoice. Here is what the common ones actually mean on Denver Metro service calls.
E17 / E13 — water fill timeout
The drum expected water and did not get enough of it in time. Usual suspects: inlet valve screens clogged with sediment — a frequent find in Denver Metro homes — a failing fill valve, a kinked hose, or a supply tap someone half-closed. If your pressure at the sink is fine, the valve or its screens are the likely culprit, not your plumbing.
E18 — drain timeout
Water would not leave inside the time limit. On a Bosch the first stop is the front-access drain filter — coins, hair ties and sock lint collect there by design. If the filter is clean and E18 returns, the blockage has moved to the pump or sump hose, the same failure family as washer won’t drain, and repeated forced drains overheat the pump motor.
E23 — leak detected (AquaStop)
Water reached the base pan and the leak-protection tripped — the one code on this list you should not ignore. The source ranges from a loose hose clamp or over-sudsing to a worn door boot or a cracked sump seal. The pan hides the leak while it works on your floor; the code is the machine protecting you.
E02 — motor fault
The drive circuit reported a problem: worn carbon brushes on older models, a wiring/connector issue, or the motor control itself. Sometimes it is a cheap brush set; sometimes it is the module. The two cost very different money — which is exactly why this code deserves a meter before a part order.
Why we don’t recommend guessing parts
E17 can be a $12 screen cleaning or an inlet valve; E02 can be brushes or a control module. Swapping parts in price order is how a $150 repair becomes a $400 one. Live diagnosis tells us which it is before anything is ordered, and our diagnostic fee is credited toward the repair.
Repair or replace?
Bosch builds washers worth fixing: valves, pumps, brushes and seals are all solidly repair-side. The honest exception is a control module on a discontinued model where the part alone approaches half the price of a new machine — we will tell you which side of that line yours is on before you commit.

Bosch Washer Code FAQ
My Bosch washer shows E18 but the filter is clean — now what?
Then the clog moved downstream: the drain pump impeller, the sump hose, or the standpipe. E18 after a clean filter is the point where opening the machine beats guessing.
Does E23 mean my Bosch is ruined?
No — it means the leak-protection system did its job. Water reached the base pan and the machine locked out to protect your floor. The leak source ranges from a loose clamp to a worn seal; the code itself is the machine working as designed.
Why does my Bosch stop mid-cycle with E17 only sometimes?
Intermittent fill timeouts usually track water pressure: a partially clogged inlet screen or a supply valve that is not fully open passes enough water on a good day and times out on a bad one.
Are Bosch washer parts expensive in the US?
Availability is good and most water-path parts are moderately priced. The cost outlier is the control module on older models — which is exactly why we test before ordering one.
