How to Start a Bosch Dishwasher (All Model Types)

Quick Answer

Bosch dishwashers with hidden top-of-door controls require a specific start sequence that is different from most other brands: select your cycle BEFORE closing the door (because the controls become invisible once the door is closed), then close the door to start. Front-control models (100/300 series) work more like other brands - load, close, select cycle, press start. Bosch does not have a dedicated Start button on most models - pressing any program button selects it, and closing the door begins the cycle. The most common reason a new Bosch owner cannot get the machine to start is trying to select a cycle after the door is already closed on a hidden-control model.

What Does the GUIDE Code Mean?

Bosch dishwashers have a less obvious start process than other brands. Here is exactly how to get it running.

Most Likely Causes

Based on aggregated repair data, here is the probability breakdown for this error code:

New owner unfamiliar with Bosch cycle-selection-before-closing design40%

Transition from a brand with a dedicated Start button24%

Accidentally pressing buttons after closing the door on a hidden-panel model (buttons are inaccessible when door is closed)14%

Control lock active preventing cycle selection12%

Delayed start accidentally set during cycle selection10%

Symptoms You May Notice

Machine does not start after closing door
Selected cycle appears cleared after door closes
No response when pressing buttons with door closed (hidden-control models)
Display shows time countdown but no wash action begins
Machine fills but does not transition into wash

Can you reset a Bosch dishwasher to clear the GUIDE code?

If a cycle is already running and you want to change cycles: open the door, hold Start/Reset for 5 seconds until the cycle clears, select the new cycle, close the door to restart. If the machine has power but does not respond to any buttons, try a hard reset by turning off the circuit breaker for 60 seconds.

Diagnostic Checklist

Follow these steps in order. We start with the easiest external fixes before opening up the machine.

Identify your panel type: hidden top-control or front-control

Close the dishwasher door and look at the front face. If you see buttons and a display on the front panel, you have a front-control model (typical of 100 and 300 series). Use the standard start procedure: load dishes, close door, select cycle, press Start. If the front face is completely blank with no visible buttons or display, you have a hidden top-of-door control model (typical of 500 and 800 series Silence Plus). On hidden-control models, all buttons are on the top edge of the door and only accessible when the door is open. The start procedure for these models is fundamentally different and described in the steps below.

For hidden-control models: open door, select cycle, then close door to start

For front-control models: load and close, then select cycle and press Start

Check for active delayed start setting

Frequently Asked Questions

Where is the Start button on a Bosch dishwasher?

On front-control models (100/300 series), there is a physical Start or Start/Reset button on the front panel - it is usually labeled clearly. On hidden top-of-door control models (500/800 series), there is no dedicated Start button. Closing the door after selecting a cycle is the start action. Some hidden-control models have a Start/Reset button on the top edge of the door that must be pressed before closing, depending on the model year - open the door and look at the top edge to see if a Start button is present.

How do I start a Bosch dishwasher with top controls (hidden panel)?

Open the door, select your wash cycle using the buttons on the top edge of the door, optionally set any additional options (extra dry, sanitize, etc.), then close the door. The cycle begins automatically when the door latches. The key point: you must select the cycle BEFORE closing the door because the controls are inaccessible once the door is shut. If you forgot to select a cycle before closing, open the door and make your selection, then close again.

I selected a cycle on my Bosch but it won't start - what's wrong?

The most common reasons: (1) Control lock is active - look for a padlock or hand symbol on the display and hold the lock button for 3-5 seconds to deactivate. (2) Delayed start is set - check if the display shows a countdown timer and cancel it by holding Start/Reset for 5 seconds. (3) Door not fully latched - push the door firmly until you hear a click. (4) Water supply valve is off - confirm the under-sink valve is fully open. (5) On hidden-control models, the door was closed before the cycle was selected - open the door, re-select the cycle, and close again.

How do I use the delayed start feature on a Bosch dishwasher?

On most Bosch models: open the door (hidden-control) or access the front panel. Select your desired wash cycle. Press the Delay button (often a clock symbol or labeled Delay Start). Each press advances the delay in 1-hour increments, typically up to 24 hours. The display will show the hours remaining until start. Close the door. The machine will start automatically after the delay elapses. To cancel a set delay: open the door, hold Start/Reset for 5 seconds, and re-start without setting a delay.

My Bosch dishwasher starts but then stops after a few minutes - why?

A cycle that starts but stops quickly usually indicates a water supply problem, a door latch fault, or an error condition. Check these in order: (1) Confirm the water supply valve under the sink is fully open - restricted flow causes a fill timeout. (2) Push the door firmly - a borderline latch can pass initial start but fail mid-cycle as vibration loosens it. (3) Open the door and check the display for an error code - E15, E24, or E25 are common causes of early cycle termination. (4) On hidden-control models, the display only shows codes when the door is open.
