Dishwasher Buttons and Symbols Explained

Dishwashers use two panel layouts. Front-control models put the buttons on the front face, which is typical of freestanding, portable, countertop, and many 18-inch slim models. Top-control or hidden-console models put the buttons on the top edge of the door, visible only when the door is open, and this layout is common on US 24-inch built-ins.

Top-control panels often have a display that shows the remaining time and indicator lights for rinse aid and lock. Compact, portable, and countertop machines usually have a short panel of roughly 4 to 6 buttons: power, cycle, start/pause, and sometimes delay. Many of them have no sanitize, half-load, or delay option, so do not expect a 12-button chart on a small machine.

Symbols are drawn by each maker, so a heat-wave icon can mean drying in progress on one panel and Extra Dry on another. A lit light and a blinking light can also mean different things, and the owner's manual of your machine is the reference for both.

The power button turns the panel on and off. On many models the panel goes to sleep after a minute or two without input, and pressing Power or opening the door wakes it.

Start or Resume begins the selected cycle. On many US models you must press Start within about 3 seconds of closing the door, or the cycle will not begin. If you miss the window, press Start again.

Pause lets you add a forgotten dish. Pause or cancel the cycle, open the door, add the dish, close the door, and press Start.

Cancel or Drain stops the cycle and pumps out the tub. It is usually a 3-second hold, and the display may show dashes while the tub drains.

Cycles set the length, temperature, and spray pattern of the wash. The same cycle carries different names across machines, and the run times below are typical ranges; your panel's display shows the estimate for your model.

Normal, Auto, or Sensor

This is the everyday cycle. It uses a soil sensor to adjust the wash, and it typically runs about 2 to 3 hours on modern US machines, with a main wash around 130 to 140°F. Use it for mixed daily loads.

Heavy or Pots and Pans

This is the longest cycle, roughly 2.75 to 4 hours. Use it for baked-on soil, greasy pans, and casserole dishes.

Quick, Express, 1-Hour, or Speed Wash

This cycle runs roughly 30 minutes to 1 hour. Use it for lightly soiled, full loads. It is not a substitute for Heavy on baked-on soil.

Delicate, China, or Crystal

This cycle uses a lower temperature and a gentler spray. Use it for fine china, crystal, and heat-sensitive items.

Rinse Only or Rinse and Hold

This cycle has no wash and no dry. It holds soiled dishes until you have a full load, and it uses very little water, as little as about 1.4 gallons on some models.

Machine Clean or Self Clean

This is an empty-machine maintenance cycle. Run it with no dishes in the tub.

Options modify the cycle you selected. They add time, heat, or water, and the panel usually shows the new estimate once you press one.

Hi-Temp Wash

This option raises the main wash to roughly 130 to 140°F. Use it for greasy loads. It adds minutes, not hours.

Sanitize, Sani-Rinse, Sani-Wash, or Anti-Bacteria

This option raises the final rinse to at least 150°F, the NSF/ANSI 184 threshold, and kills 99.999% of food-soil bacteria. It can add up to about 1.5 hours. Sanitize is not sterilization, which needs around 250°F. Use it for baby bottles, cutting boards, and a monthly deep clean.

Heated Dry

This option adds roughly 30 minutes and uses more energy than air dry. Use it when you need dishes dry right away.

Extra Dry, Dry Boost, Dry+, or Extended Dry

This option gives longer, hotter drying and adds roughly 30 to 50 minutes. It helps with plastics, which hold water.

Air Dry

This option uses no heater. It is free but slow, about 60 to 90 minutes in-cycle, or several hours if you leave the door ajar.

Half Load, Upper Rack, Lower Rack, or Wash Zones

This option washes one rack only. Use it only if you routinely run partial loads, since a full load is more efficient.

Delay Start

This option delays the cycle, typically 1 to 12 hours and up to 24 hours on some models. You must still press Start to arm it.

Extra Rinse

This option adds a rinse. Use it for hard water or heavy soil.

Steam or Steam Prewash

This option loosens dried soil and adds up to about 30 minutes.

System buttons control the panel itself rather than the wash. They are the source of most "dead panel" confusion.

Control Lock or Child Lock

This locks every button except Power, usually with a 3-second hold. It does not lock the door and does not drain the tub. It is the number-one reason a dishwasher "won't turn on." The activation combo varies by model, sometimes two buttons held together, so the manual is the reference.

Chime on/off

This turns the end-of-cycle beep on or off, often with a 3-second combo. A silent panel is not a broken panel.

Smart Control or Wi-Fi

This connects the appliance to an app. The button enables remote start.

Sabbath mode

This keeps the appliance usable without operating lights or displays on the Sabbath. It can make buttons appear unresponsive.

Demo mode

This is a showroom mode that makes the panel light up without running. It is a cause of "buttons do nothing."

The same function appears under different labels and icons across the market. This table maps the function to the names you may see on a panel.

These are typical ranges. Your panel's display shows the estimate for your model, and the manual gives the exact figures.

Work through these checks in order. Most "dead panel" cases end at the first step.

1. Control Lock. Look for a padlock light or "CL" on the display, then hold the lock combo for 3 seconds.
2. Sleep or standby. Open and close the door or press Start to wake the panel.
3. Delay Start counting down. The machine is waiting, not broken.
4. Door not latched. Press Start and close the door within about 3 seconds.
5. Breaker or GFCI. Reset at the panel or the GFCI faceplate.
6. Water supply valve. Check that it is open under the sink.
7. Sabbath or Demo mode. Check the manual for how to exit.
8. Touchpad or control board. If the display works but some buttons do not, it is the touchpad. If nothing lights at all, it is power, the door switch, or the main board. At this stage, call service.

Most dishwashers have no dedicated reset button. A reset means cutting power: unplug the unit or switch the breaker off for about 30 to 60 seconds, then restore it.

Blinking lights usually mean the door was opened mid-cycle or power was interrupted, not a fault. A backwards lower rack can stop the door from latching, which reads as "buttons won't work."

Modern machines use about 3 to 4 gallons per cycle, and pre-rinsing can waste around 20 gallons. Scrape, don't rinse. Run full loads and use Normal or Sensor for everyday dishes. Turn heated dry off or use air dry to save energy, since heated dry uses at least about 15% more energy.

Use Sanitize monthly or for baby bottles and raw-meat boards. Use Half Load only when you genuinely can't fill the machine. For context, ENERGY STAR sets standard models at 240 kWh/yr and 3.2 gal/cycle or less, and compact models at 155 kWh/yr and 2.0 gal/cycle or less.
