Quick Answer: Resetting a Bosch Dishwasher#
Bosch machines carry two different recoveries and they are not interchangeable. Holding the Start button for three to four seconds runs the built-in drain, which empties the tub and cancels the programme. Cutting the circuit at the breaker for a minute reboots the control module, which is a different thing and the only option when the panel has stopped responding at all — Bosch dishwashers are wired in, so there is no plug to pull.
Which of the two you can actually use depends on the panel in front of you, and where the drain countdown appears differs by range. The table below matches the panel to its reset, and — more usefully — names what that reset will not repair, because both moves reboot logic and neither one moves a blockage or wakes a seized pump.
Match your panel to its reset — and to what that reset cannot fix#
Find the row that describes the panel you are standing in front of. The right-hand column is the point of the table: both Bosch resets act on the control logic, so anything mechanical downstream survives them untouched and will come straight back on the next cycle.
| The panel in front of you | The reset it carries | What it will not repair |
|---|---|---|
| 100 or 300 Series, plain indicator lights, no time display | Hold Start three to four seconds; the drain runs and the indicator marks the countdown | Standing water that returns — that is the filter, check valve or pump |
| 500, 800 or Benchmark, with a time display or InfoLight | The same Start hold; the countdown appears on the time display or the projected light | A door that will not latch, which stops the panel arming in the first place |
| Fully integrated, every control along the top edge of the door | The same Start hold, read with the door tipped open far enough to see the top edge | Nothing about the drain path; the countdown only tells you the pump was asked to run |
| Older Ascenta panel | Not the Start hold — a paired Cancel and Drain sequence | Anything at all if you keep holding Start; on this range that gesture does nothing |
| Panel completely unresponsive, no lights, no beep | The breaker only, for a full minute — there is no plug to pull | A failed control module, which comes back dark after the reboot too |
| Lock or key symbol lit on the display | Not a reset: the dedicated child-lock button, held until the symbol clears | Nothing is wrong to repair — the machine is doing what it was told |
If the Start-hold drain runs to completion and water is still standing afterwards, stop resetting. The logic has already done everything it can, and each repeat only re-runs a pump against the same blockage.
Where these rows come from: the range differences this page already sets out — 100 and 300 against 500, 800 and Benchmark, fully integrated panels, and the Ascenta exception — plus the child-lock button it warns not to confuse with the Start hold. They are keyed on the panel you can see rather than on the model number, because the number is on the inside of the door and the panel is not. No frequency is claimed for any row; Bosch publishes no breakdown of which panel generation is in service, so this table counts nothing.

How to Reset a Bosch Dishwasher (Step by Step)#
- For a Bosch dishwasher, the fastest reset is the built-in one: press and hold the Start button (marked Start on most panels) for three to four seconds — the display shows a drain time and the pump runs to clear the cycle.
- If the panel is still unresponsive, cut power at the breaker or under-sink switch, since Bosch units are hard-wired.
- Wait one minute with the power off so the Bosch control module fully resets, then restore power.
- Open and close the door once and confirm the panel lights and the program buttons respond.
Bosch Dishwasher Model Variations#
Where the drain countdown appears depends on the range — 100 and 300 Series units show it on a plain indicator, while 500, 800, and Benchmark models render it on the InfoLight or the time display. The child lock is its own dedicated button, so do not confuse it with the Start-hold drain. Fully integrated Bosch units carry every control along the top door edge, and older Ascenta panels swap the Start hold for a paired Cancel and Drain sequence.
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 a Reset Doesn't Fix Your Bosch Dishwasher#
If water keeps pooling after the Start-hold drain, the cause sits downstream of the electronics — usually the drain pump, the check valve, or a clogged filter. Read any surviving code against our Bosch error-code guide, then follow the dishwasher-not-draining, will-not-start, and water-in-the-bottom symptom pages. A reset only reboots the logic; it cannot move a blockage or wake a seized pump.

Bosch Dishwasher Reset FAQ#
How do I reset a Bosch dishwasher?
Press and hold Start for three to four seconds to trigger the built-in drain and clear the cycle, and if the panel is still frozen, switch the circuit off at the breaker for a minute before restoring it. Bosch units are hard-wired, so there is no plug to pull.
How do I drain a Bosch dishwasher with the Start button?
Holding Start for a few seconds tells the machine to skip to its drain phase; the display shows a short countdown while the pump runs. Once the tub is empty the cycle is cancelled and the panel returns to ready.
Why is there water in the bottom of my Bosch dishwasher?
A shallow pool of water is normal to protect the seals, but a full standing pool after a drain hold points to a blocked filter, a kinked hose, or a weak pump. Clean the filter basket first, since it is the most common culprit.
How do I turn off child lock on a Bosch dishwasher?
Locate the separate button marked with a lock or key and hold it until the lock symbol clears from the display. It is a different control from the Start button used for draining.
Why will my Bosch dishwasher not start?
A Bosch that stays silent usually has a door that is not fully latched or has lost power at the breaker, since the panel cannot arm until the door switch closes. Press the door firmly shut and confirm the circuit is live before suspecting the board.
