Expert Bosch Dishwasher Repair in NYC | Fast & Guaranteed

Bosch Dishwasher Error Codes

Error codes are shortcuts: they point to the subsystem that needs attention. Use the guidance below to decide what’s safe to try, what to capture for us, and when to stop.

E15 — leak detected (water in base tray)

What it means: The float switch in the bottom pan rose; the machine is protecting itself.
Do now: Turn off the water under the sink and switch the breaker off. Don’t keep running “to see if it clears.”
Common sources: Door gasket splash, loose clamp at inlet valve, sump or heat-pump seal seep, drain hose joint, or a kinked/abraded line rubbing on cabinetry.
What helps us: A photo under the sink (supply + drain routing) and any visible drip points.
Typical fix: Dry the base, trace the source (UV dye/paper tests), reseal/replace gaskets or fittings, then run an extended leak test. In elevator buildings we also place pads/pans to satisfy COI and management risk policies.

E22 — filter blocked

What it means: Residual water in the sump because the filter is clogged or not seated.
Quick check: Remove and rinse the filter set, wipe the sump channel, lock the filter back in with a firm clockwise twist.
If it keeps returning: Build-up in sump channels, circulation debris, or a mis-fitted cover can masquerade as “just a dirty filter.” We’ll deep-clean the sump path and verify flow.

E24 / E23 / E25 — drain family

• E24 — not draining (path restriction).
  DIY checks: Confirm the high loop or air gap; clear the disposal knockout (new disposals ship with it closed); inspect hose kinks or long horizontal runs.
  Tech work: Pressure test the path, check check-valve behavior, and correct routing.
• E23 — drain pump fault (motor/jam).
  Signs: Buzzing or hum with no water movement.
  Tech work: Inspect for glass pits/seeds, test pump under load, replace pump if windings/bearings fail.
• E25 — pump cover/impeller blocked.
  Quick check: Reseat the pump cover in the sump and make sure debris isn’t holding it ajar.
  Tech work: Verify wear ring clearance and that the seal mates properly.

What helps us for the drain family: A clear photo under the sink showing the entire hose run and air-gap/high-loop; tell us if a disposal was recently replaced.

E14 — flow meter / fill system

What it means: The control isn’t seeing expected pulses from the flow sensor during fill.
DIY checks: Valve fully open? Inlet hose kinked? Mesh screen clogged?
Likely causes: Weak inlet valve, scaled or failed flow meter, wiring issues in the harness, or low building water pressure.
Tech work: Measure flow pulses, verify 120V at the valve, test the AquaStop assembly, and inspect wiring paths that flex at the hinge.

E09 — heat-pump heater fault

Symptoms you’ll notice: Cycles complete but dishes are cold/wet; sometimes mid-cycle stops.
What it means: The heater integrated into the circulation pump isn’t within spec or isn’t energized.
Safety: Don’t bypass or jumper—risk of damage.
Tech work: Electrical checks (supply under load, heater resistance), verify temperature rise through phases, inspect for scale in the loop; replacement is often a complete heat-pump module for reliability.

E06 — door sensor / latch circuit

What it means: The machine thinks the door isn’t safely detected.
DIY checks: Make sure the panel isn’t twisting the door, latch isn’t misaligned, and child lock isn’t active.
Tech work: Adjust/replace latch components, inspect harness strain where the cable bends near the hinge, and re-square the mounting if the cabinet pull is torquing the panel.

E07 / E10 / E12 — CrystalDry/Zeolite drying system

What it means: Air movement or chamber heating in the zeolite system isn’t correct.
Quick wins: Keep rinse-aid ON; don’t block vent paths with tall items; run a sanitize/high-temp cycle periodically.
Tech work: Check fan spin, thermistors, chamber heater, and airflow baffles; clean or replace affected components. Poor detergent or hard-water settings can amplify symptoms—we’ll set the hardness and dosing correctly.

E21 / E0103 / E0110 — control, relay, communication

What it means: The control isn’t getting expected feedback from a motor/relay or there’s a comms fault between boards/UI.
Context: Can appear after surges, moisture in the UI, or intermittent wiring faults.
Tech work: Inspect for water ingress at the console, test relays and load paths, reseat connectors, and update/replace boards as needed. If your model has Home Connect, logs help us correlate “when it failed” with what was active.

E27 — low mains voltage

What it means: Supply voltage sagged below spec.
Quick checks: No extension cords or power strips; share the circuit with fewer loads; in older buildings, outlets and runs can be marginal.
Tech work: Measure voltage under load, verify terminal block condition, and recommend an electrician if the branch circuit is unstable.

What to capture before you book

• Photo of the error on the display (or exact text).
• Model and serial (E-Nr/FD label on the door frame).
• Short clip (10–15s) of the symptom (drain noise, beeps, leak area).
• Under-sink photo showing supply valve, air gap/high loop, and disposal connection.
• Recent changes (new disposal, recent plumbing, panel install, power flicker).

When to stop DIY

If there’s water in the base pan, a burning smell, tripping breakers, or repeated error returns after basic checks, pause. Those conditions escalate fast in NYC apartments and co-ops; we’ll handle the leak/heat/electrical diagnostics with the right parts on hand.

Bosch Drain & Leak Triage (E24 / E15) — NYC Edition

A fast, safe decision block designed for real Bosch owners in Brooklyn & Manhattan.

When to use this: Standing water, E24 (drain), E15 (leak), sour odor, or cycle aborts.

60-Second Safe Self-Check (no tools)

1. Kill power at the breaker if you see leaks or smell burning.
2. Open the filter and remove debris from the sump screen.
3. Sink/air-gap check: Run the faucet and disposal; clear the air gap if present.
4. High loop: Confirm the drain hose rises to the underside of the countertop; no kinks behind the unit.
5. Retry a drain (Cancel/Drain). If water remains or the error returns, stop and book service.

What the codes usually mean on Bosch

• E24 (won’t drain): Most often filter/sump debris, blocked hose/air-gap, or disposal knockout left in after install. Pump faults are less common but possible. Bosch Home Appliances+1
• E15 (leak detected): Water in the base pan triggering the safety float—caused by internal leaks or oversuds/overfill. A hard reset may clear the code briefly; the leak still needs diagnosis. PartSelect

NYC install pitfalls we see a lot

• Newly added disposal with knockout not removed → total drain block.
• Hose crushed behind tight cabinetry; missing high loop → backflow/odor.
• Air-gap/tailpiece clogged with food sludge. Better Homes & Gardens

Why Bosch series matter (ID your platform)

• 300/500/800/Benchmark differ in pump, tub, drying, and sensors—this guides parts, labor time, and expected outcomes. Snap a photo of the E-NR model tag; we’ll match the exact platform. Yale Appliance Blog+1

Bosch Fill & Water Supply Triage (E18 / E14) — NYC Edition

A fast, safe decision block designed for real Bosch owners in Brooklyn & Manhattan.

When to use this: No or slow fill, the cycle stalls early, E18/E14, machine sounds “dry,” or dishes come out dusty from lack of rinse water.

60-Second Safe Self-Check (no tools)

1. Safety: If you see any leak or smell burning, switch off the breaker and stop.
2. Water supply: Fully open the dishwasher’s shutoff valve under the sink (angle stop). Many “no fill” calls are a half-closed valve after plumbing work.
3. Hose path: Make sure the inlet hose/AquaStop isn’t kinked or crushed behind the cabinet.
4. Inlet screen: Turn off water, then briefly disconnect and visually check the small mesh screen at the hose or valve end (if accessible). Clean out sand/scale; re-tighten firmly.
5. Prime hot line: Run the sink hot water for 30 seconds, then start a quick cycle to test.
   If E18/E14 returns or filling still stalls, stop and book service.

What the codes usually mean on Bosch

• E18 (fill timeout/low water): Supply closed or restricted, clogged inlet screen, low building pressure, or a failing inlet valve.
• E14 (flow sensor/inlet error): Debris or scale in the flow meter/water softener path, wiring fault, or a control/valve issue causing incorrect flow readings.

NYC install pitfalls we see a lot

• Angle stop left partially closed after countertop/disposal installs.
• RO/inline filters choking flow; not enough GPM for a proper fill.
• Tight cabinetry pinching the AquaStop hose when the unit is pushed back.
• Water hammer in older buildings intermittently tripping fill protection.

Why Bosch series matter (ID your platform)
300/500 vs 800/Benchmark differ in inlet assemblies, AquaStop design, internal softener/flow meter routing, and control logic—this affects parts and labor time. Snap a photo of the E-NR model tag; we’ll match the exact platform.

What we do on arrival (diagnostic flow)
Water pressure and flow test at the valve → inlet screen inspection → coil resistance and live-command test on the inlet valve → flow meter signal verification and softener path checks (if equipped) → control output and wiring validation → full fill/wash/drain verification.

If parts are needed, we install OEM only and confirm a complete hot wash and proper fill levels.

Scheduling & guarantee

• $99 diagnostic credited toward the repair.
• Same-day/next-day in Brooklyn & Manhattan (below 96th St).
• 180-day parts & labor warranty.
• Arrival windows: 9–11 / 11–1 / 1–3 / 3–5.
