Dishwashers from major brands share a core set of programs. Names vary a little, but the logic is the same. Sensor-driven machines adjust time and heat on the fly, so runtimes can stretch—by design—when water is cooler, soil is heavier, or options like sanitize and heated dry are active.
| Cycle | What it does | Best for | Avoid if | Typical trade-offs |
|---|---|---|---|---|
| Auto/Sensor | Adjusts time/heat via sensors | Mixed daily loads | You fully pre-rinse | Can run long on cool water |
| Normal/Daily | Balanced wash/dry | Plates, cups, utensils | Baked-on pans | Longer on modern, efficient units |
| Heavy | Higher heat & stronger spray | Casseroles, dried protein | Thin glass | Longest runtime |
| Eco | Minimal water/heat | Light, pre-scraped loads | Starches, heavy soil | Long + may need extra dry |
| Quick/Express | Short cycle for fresh soil | Brunch plates, glassware | Dried or baked-on food | Cleans lightly; not for sanitizing |
| Delicate/China | Lower heat/gentler spray | Thin stemware, light plastics | Heavy soil | May leave heavy items under-washed |
-
Auto / Sensor: Uses turbidity and temperature sensors to tailor wash time, water use, and heat. Choose it for mixed loads when you want the machine to decide. Many models let you tweak sensor sensitivity in settings.
-
Normal / Daily: Targets typical dinner plates, cups, and utensils with moderate soil. It often runs longer on modern machines to save water and energy, then compensates with efficient spray patterns.
-
Heavy / Pots & Pans: Higher temperatures and more aggressive spray for baked-on pans, casserole dishes, and dried protein. Expect the longest runtimes.
-
Eco: Prioritizes reduced water and heat. Good for daily use if you are patient and pre-scrape. Not ideal for stubborn starches. Label may vary by brand.
-
Quick / Express: Short, hot burst for lightly soiled glassware and plates. Skip if food is dried on or if you need sanitization.
-
Delicate / China: Gentler spray and lower heat for stemware and light plastics that are marked dishwasher-safe.
-
Sanitize (option): Raises final-rinse temperature and hold time to meet hygiene targets when paired with compatible cycles on many models. Good for baby items and cutting boards that are rated dishwasher-safe. Requirements vary by brand and model; confirm in your manual.
Field insight
If you rinse everything spotless before loading, sensors often assume the load is clean and cut the cycle short—then glasses film over later. Instead, scrape and load; let the sensors see light soil so the machine doses correctly.
Choose the Right Cycle for Local Water, Power, and Loads
Because kitchens here typically run on 120 V/60 Hz supplies, electric heating ramps more slowly than in some regions. Consequently, cool incoming water—especially in winter—will lengthen sensor and normal cycles as the machine raises temperatures. That is expected behavior, not a fault.
Hard water is common in many municipalities, and it changes everything. Use rinse aid year-round, and adjust the dispenser one step higher if you notice spotting after switching detergents. If your model supports an extra dry or sanitize option, enable it on heavy ceramic loads or when the kitchen runs cool; the machine may increase final-rinse heat and extend drying to compensate. Brand guides confirm that options add time but improve specific outcomes.
Modern autosense programs are excellent for mixed family loads. However, choose Heavy for baked-on pans, Delicate for thin glass, and Quick only for brunch plates and fresh soil. On select models, Bosch documents adjustable sensor sensitivity; a technician can help you set this if you consistently see under- or over-washing.
Local practicality
In colder months, run the sink hot for 10–15 seconds before starting a cycle so the first fill is not icy; this helps sensors stabilize faster. In open-plan condos, schedule cycles for off-peak hours and use eco or quiet modes where available.
Pro Setup and Safe Use
Dishwashers are simple to use, yet installation details decide whether programs can perform. From our service calls, these are the preventable issues we see most often—and how to avoid them.
-
Pre-start checklist (five minutes): Confirm a raised drain loop under the counter, check that the inlet hose is not kinked, verify the shut-off valve opens fully, ensure the unit is level front-to-back and side-to-side, and top up rinse aid. These steps reduce mystery long cycles and poor drying more than any detergent change.
-
Safety and compliance essentials: Use an outlet with a proper equipment grounding conductor and a dedicated circuit sized for the nameplate current. Do not alter the factory cord or bypass a junction box. Follow the local electrical code; the Electrical Safety Authority publishes the adopted code and technical guidelines for safe installations. If you are changing wiring or relocating the machine, hire a licensed electrician.
Water and plumbing notes
Where a municipality requires backflow protection for certain premises, plan the air gap or device location before you push the cabinet back. Some cities publish permit guidance for backflow devices and related plumbing work; check local rules or consult a licensed plumber if in doubt.
Product safety and certification
Look for a CSA mark on the rating label; it indicates third-party certification to applicable standards for household dishwashers and is recognized by authorities having jurisdiction.
Troubleshooting Results Without Guesswork
If glasses look cloudy, first confirm you are using rinse aid and the correct detergent dose for your water. Next, choose Auto or Normal with sanitize and heated dry for a few cycles to reset expectations. Manufacturer guidance notes that longer runtimes on these cycles are normal and often necessary for proper cleaning and drying.
Loading matters more than cycle choice. Angle bowls so spray can shed; keep tall items away from the detergent cup; and clip lightweight plastics so they do not block the spray arms. If you suspect under-heating, remember that sensor machines add time and heat automatically when inlet water is cool or soil is heavy.
Error codes are not solved by repeated resets. For example, door-latch or fill errors return until the underlying issue is fixed. Check the manual for your exact model and follow the specific steps. If a code points to a heater circuit, control board, or signs of a leak, stop using the appliance and book a licensed technician. Electricity and water do not mix, and opening panels may affect warranty coverage.
One-Minute Care Routine
Do this after every grocery-run cycle and, moreover, before heavy holiday loads:
-
Refill rinse aid, wipe the flat filter, spin both spray arms by hand to feel for grit, and run the hottest cycle once a month with machine cleaner if you use a lot of starches. Additionally, leave the door ajar for a few minutes after cycles to vent steam and protect cabinets.
When to Call a Pro
If you see tripped breakers, scorch marks, leaks at the inlet elbow, or a wet base pan—stop. Shut the valve, unplug or switch off the breaker, and book service. Electrical work and any gas connections for combo installations must be handled by licensed trades. Following the local electrical code and accepted product standards keeps homes safe.

FAQ
How do I get the fastest acceptable wash on a weeknight?
Use Quick or Express only for fresh food soil. Otherwise, Auto with heated dry off is the better compromise; it adjusts time and heat and still protects glasses. Whirlpool and GE note that options like heat boosts and sanitize add time; turn them off when speed beats sparkle.
Do I need to rinse dishes first?
No—scrape well and load. Sensor cycles depend on a little soil to judge how much work to do. Full pre-rinsing can trick the machine into under-washing.
Which cycle is best for baby items and cutting boards?
Use a compatible cycle with the sanitize option enabled. Many models allow sanitize on Auto, Normal, or Heavy; check your manual for the exact pairing and required parameters.
Can I mix glassware and pots?
Yes—run Auto or Normal with rinse aid, and add Heavy only when pots have baked-on residue. For thin glass, Delicate keeps spray gentler.
My winter cycles take forever. Is something wrong?
Likely not. Cool inlet water lengthens sensor and normal cycles while the machine brings temperatures up. That behavior is expected.
