Thermador dishwashers
Sapphire glow, Bosch bones, honest E-codes.
Thermador's Star-Sapphire, Sapphire and Emerald dishwashers ride the proven BSH platform - which means real, officially published E-codes instead of folklore. E15 leak protection and the E24 drain family account for most calls, and both have documented, testable paths.
A photo of the model label and the complete installation helps the team understand the configuration before the visit.
Flagship
Star-Sapphire
StarDry with zeolite drying, glow projection and the top LCD - the coded flagship.
Core
Sapphire
Premium wash systems and Chef's Tool Drawer on the same E-code platform.
Entry
Emerald
The accessible line, sharing hydraulics and code dialect.
Legacy
Topaz and earlier
Older DWHD machines, still coded, still serviceable.
Start with the symptom
Common Thermador dishwasher problems
A symptom narrows the inspection; it does not identify the failed component. The $99 visit confirms the actual fault on the exact model before any repair is authorized.
Water
Standing water after a cycle
The E24 family - filter, pump, hose, air gap in documented order.
Symptom
Dishes wet on plastic
StarDry zeolite health on Star-Sapphire; rinse aid and heater on the rest.
Surface
White film on glassware
San Diego hard water versus the built-in softener settings.
Washing
Cycle stops mid-wash
Photograph the code - the LCD is the best witness this platform offers.
Door
Door won't latch on panels
Panel weight and latch alignment on integrated installs.
Symptom
No fill, quiet machine
E14/E16 territory - supply, valve and flow meter tested in order.
Series and model numbers
Thermador dishwasher series we service
One BSH-rooted platform in three trims - the E-Nr from the door edge decides parts, and the code on the LCD decides where the visit starts.
Star-Sapphire
DWHD770-class
Model numbers
DWHD770WFP
What to note
Zeolite StarDry hardware has its own official codes (E2120, E2130).
Sapphire
DWHD660-class
Model numbers
DWHD660WFP
What to note
Panel-ready and stainless variants share the platform.
Emerald
DWHD560-class
Model numbers
DWHD560CFP
What to note
The E-Nr and FD number from the door tag decide exact parts.
Model label
Where to find your Thermador model number
The model tag (E-Nr) is on the top edge of the dishwasher door, visible when the door is open. Photograph the full tag including the FD number - both are needed for exact parts. Photograph the complete label — the full model and serial identify parts and production year better than the series name alone.
Indicators and alerts
Thermador dishwasher alerts & indicators
For any message not shown, use the manual for the exact model rather than a generic list.
Message / alert
E15 with water in the base
What it means
Leak protection tripped - the float in the base pan found real water.
Safe check
Close the water valve, protect the floor and book with priority - E15 does not clear until the leak is found and the pan is dry.
Thermador diagnostics
Thermador dishwasher error codes, decoded.
Every code above appears in Thermador's own published dishwasher error-code list; E09's element meaning is additionally confirmed by independent service sources on the shared BSH platform. Codes are read from the display, not guessed from symptoms.
Error code · E15
Water in the base pan
What it commonly means
Official meaning: the safety switch detected water in the base - a real leak somewhere in the machine.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
The source is located, the pan dried, and a full cycle verified before the code is cleared.
Error code · E22 / E24 / E25
Drain family
What it commonly means
Officially documented drainage faults: blocked filter, blocked or faulty drain pump, kinked hose or a clogged air gap.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
The drain path is walked in order - filter, pump, hose, air gap - most cases end at the first two.
Error code · E14 / E16 / E17 / E18
Fill and flow sensing
What it commonly means
Official meanings: flow-meter failure or trouble with water flowing into the machine.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
Supply, inlet valve and flow sensor are tested in order; San Diego scale is a repeat offender.
Error code · E04
Heater electronics fault
What it commonly means
Official meaning: the self-test found faulty heater electronics.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
The control's heater circuit is tested at the board - distinct from the element itself.
Error code · E09
Heating element fault
What it commonly means
The flow-through heater failed - confirmed across the BSH service literature and independent sources.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
The heater and its relay are tested directly; no heat also explains poor drying.
Error code · E2120 / E2130
StarDry zeolite system
What it commonly means
Official Star-Sapphire codes: zeolite chamber heater or fan faults in the drying system.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
The zeolite heater and fan are tested per the official documentation - a Star-Sapphire specialty.
Any other code or behavior
Meanings vary by series and year
Why we do not guess
Thermador products span several control generations; the same characters can mean different things on different series. The complete model number fixes the definition.
What to capture
Photograph the full display and the model label, and note what the appliance is doing.

Preventive service and owner care
Thermador dishwasher maintenance
Alpha Pro provides preventive and general maintenance for Thermador dishwashers. The appliance design determines which procedures are accessible and appropriate.
Owner maintenance
Routine care between visits
Filter: remove and rinse the filter assembly regularly - the single most effective owner step.
Door seal: wipe the gasket and lower lip; check for debris that prevents sealing.
Loading and detergent: follow the manual for detergent and rinse aid; avoid blocking the dispenser.
Professional maintenance
Inspection follows the appliance design
A professional visit can evaluate accessible systems without assuming every procedure applies to every model.
Fill, wash, and drain performance
Circulation and drain pump condition
Heater and drying performance

Diagnosis before parts
A straightforward three-step service process
1
Describe the symptom
Call or book with the model label, exact behavior, any displayed codes, photos, and access notes.
2
Evaluate the system
The technician examines the reported condition in context: fill, wash, drain, drying, controls, leaks, and relevant components.
3
Review the recommendation
Findings and proposed work are explained before repair proceeds. The residential diagnostic is credited toward an approved repair.
Service area and operating context
Thermador dishwashers across Poway
Poway sits in the hills off I-15 - ranch properties of Old Poway, gated Green Valley, newer streets off Espola Road. Garage refrigerators fight summer heat, canyon dust clogs condensers, and hard water leaves scale in ice makers and washer valves.
Inland heat and hard water set the pattern here: garage refrigerators work hardest in summer, dust clogs condensers, and scale builds in ice makers, dishwashers and washer valves.
During maintenance, accessible metal surfaces can be inspected for corrosion, moisture exposure, or conditions that may warrant attention. Location alone does not establish the cause of a failure.

Helpful answers
Thermador dishwasher service questions
Clear preparation makes a service request easier to evaluate.
Do you offer same-day Thermador dishwasher repair in Poway?
Yes - same-day windows are offered across San Diego County subject to the day's schedule. Availability is confirmed for the exact address when you book.
Do you service my street in Poway?
We take requests across Poway (ZIP 92064, 92074). Share gate codes, parking or building access when booking so the technician can plan the visit.
Does the $99 residential diagnostic fee always apply?
Yes. It is non-refundable and credited toward the total repair cost if you proceed. There are no residential exceptions.
What warranty comes with a repair?
A 90-day labor warranty and a 1-year parts warranty, both starting on the date the repair is completed.
Can a symptom alone identify the failed part on a Thermador dishwasher?
No. A symptom narrows the search, but the diagnostic visit on the exact model confirms the actual fault before any repair is authorized.
What does E15 mean on my Thermador dishwasher?
Leak protection: water reached the base pan and the float cut normal operation. Close the supply and book - the code stays until the leak is found and the pan is dried.
My Star-Sapphire stopped drying well - why?
StarDry uses a zeolite chamber with its own heater and fan, and both have official codes (E2120, E2130). The system is testable - drying complaints on this machine are diagnosable, not mysterious.
What is the most common Thermador dishwasher repair?
The E24 drain family - filter and pump - followed by heater faults (E04/E09). Both are documented, parts-backed repairs.
Where is the model number?
On the top edge of the door, visible when open. Photograph the E-Nr and FD number together.
Do you service the older Topaz machines?
Yes - earlier DWHD generations share the coded platform, and parts are ordered from the exact E-Nr.
