Are all Whirlpool dishwashers the same size?
No. Whirlpool dishwashers come in multiple size categories, and even built-in models can vary by width and depth. For your Whirlpool WDT780SAEM2, plan on a standard built-in opening in most kitchens, then confirm the exact cutout and hookup clearances in the WDT780SAEM2 installation guide.
Most Whirlpool dishwashers fall into these groups:
- Standard built-in: most common; designed for standard cabinetry openings
- Compact built-in: narrower for small kitchens
- Oversized/tall-tub built-in: similar width but can need specific depth and clearance planning
- Portable: typically deeper and taller than built-in units
Even when the width is “standard,” small differences matter for fit, noise, and leaks.
- Cabinet opening width (side-to-side)
- Opening height (floor to underside of countertop)
- Opening depth (front of cabinet to back wall)
- Toe-kick height and depth
- Water line, drain hose, and electrical routing space
| Item to check | Why it matters | Where to confirm |
|---|---|---|
| Cutout width/height/depth | Prevents binding, vibration, and door interference | WDT780SAEM2 installation guide |
| Drain routing and high loop | Helps prevent backflow and draining issues | WDT780SAEM2 installation guide |
| Water supply connection space | Avoids kinks and leaks at the inlet connection | WDT780SAEM2 installation guide |
Dishwashers are built to fit common cabinet openings, but installation clearances and hose routing vary. Measuring first helps your WDT780SAEM2 sit level, seal correctly, and drain properly.

How to change the bottom seal on a Whirlpool dishwasher?
On a Whirlpool dishwasher like model WDT780SAEM2, replacing the bottom (lower) door seal typically means removing the lower access panel, taking off the old seal from the bottom edge of the door or tub lip (depending on design), then pressing the new seal fully into place so the door closes evenly and doesn’t leak. Use the WDT780SAEM2 installation guide for safe access-panel removal and reinstallation steps.
- Turn off power at the breaker; dishwashers use line voltage.
- Shut off the water supply valve under the sink.
- Pull the toe-kick or lower access panel so you can see the bottom front area.
- Have a towel ready; a small amount of water can spill when you work near the tub.
- Take a quick photo of the bottom edge area before removing anything.
- Remove the lower access panel (toe panel). The installation instructions show how the panel fasteners/screws reinstall and how the panel should sit against the floor.
- Inspect where the seal sits. Some Whirlpool designs use a press-in seal along the bottom edge; others use a deflector style piece. Clean the channel or mounting surface.
- Remove the old seal. Pull it straight out; avoid scratching the tub lip or door edge.
- Install the new seal. Start at one end and press it in evenly across the full length; make sure corners are fully seated.
- Reinstall the access panel. Confirm the lower edge touches the floor and fasteners are locked.
- Test for leaks. Run a short cycle and watch the bottom corners and center.
- Door not closing square: verify the unit is level and aligned in the opening.
- Door dropping too fast: adjust door spring tension so the door closes firmly and evenly.
- Seal not fully seated: re-press the seal into the channel, especially at corners.
- Suds overflow: use dishwasher detergent only and avoid overfilling.
| What you see leaking from | Common culprit | What to check |
|---|---|---|
| Bottom center/front | Lower door seal or deflector | Seal seated flat, no gaps |
| Bottom corners | Door alignment or hinge tension | Leveling, spring tension |
| Under the unit | Sump seal or hose | Clamps, cracks, loose fittings |
A properly seated lower door seal prevents leaks that can damage flooring and helps the dishwasher maintain correct wash pressure for better cleaning.

How to fix F2 E2 on Whirlpool dishwasher?
On the Whirlpool WDT780SAEM2, the F2 E2 error points to a user interface (keypad) and control communication problem. We fix it by doing a hard reset first, then checking the console wiring connections; if the error returns, the console assembly or electronic control typically needs replacement.
- Turn off power at the breaker for 5 minutes, then restore power.
- Make sure no keys are stuck; press each key once to confirm it moves freely.
- If the dishwasher beeps and will not respond, cancel the cycle and restart.
- If the error appears right after closing the door, verify the door is fully latched.
- If the unit is dead or intermittent, confirm the house supply is stable (breaker not tripping).
- Shut off power at the breaker.
- Open the door and remove the inner door screws to access the console area (follow the steps in the WDT780SAEM2 installation guide).
- Reseat the ribbon connector and wire harness plugs between the user interface and the control.
- Look for corrosion, moisture tracks, or pinched wiring along the top of the inner door.
If reseating connections does not stop F2 E2, replacement is usually the next step.
| Symptom | Most likely fix | Why |
|---|---|---|
| Some keys do not respond | Replace console/user interface | Keypad circuit is failing |
| Random beeping or phantom key presses | Replace console/user interface | Moisture or shorted keypad matrix |
| Error returns after power reset and reseating plugs | Replace electronic control board | Control is not reading UI data reliably |
When the control cannot reliably read the keypad, the dishwasher can stop mid-cycle, ignore selections, or run the wrong options. Fixing the connection or replacing the failed control component restores normal cycle selection and prevents repeat shutdowns.
Use our Whirlpool dishwasher error codes reference to confirm the exact meaning of F2 E2 and related codes that can appear with it.

What is the most common problem with a Whirlpool dishwasher?
The most common issues we see on Whirlpool dishwashers like model WDT780SAEM2 are poor cleaning, not draining (standing water), or not starting. These problems usually trace back to loading and detergent issues, a clogged spray path, or a failing drain or wash component; check the WDT780SAEM2 owner's manual troubleshooting section first.
- Dirty dishes after a cycle: spray arm holes blocked, poor loading, low water temperature, or detergent not dispensing
- Standing water in the tub: drain path restriction, kinked hose, or a weak drain pump
- Won’t start or stops mid-cycle: door not fully latched, power interruption, or control not completing a cycle
- Suds or overflow: wrong soap type or too much detergent (hand soap or laundry detergent causes heavy suds)
- Poor drying: no rinse aid used, plastics holding water, or Heat Dry not selected
- Confirm the door closes tightly and latches; a loose latch can stop the cycle.
- Verify power at the dishwasher (breaker/fuse) and that the water shutoff valve is open.
- Use only automatic dishwasher detergent; avoid hand-washing soap to prevent suds.
- Improve drying by using rinse aid and selecting Heat Dry; unload the bottom rack first.
- If water remains, inspect the drain hose routing for kinks and check for a blockage at the sink/disposer connection.
| Symptom | Common part involved | What it affects |
|---|---|---|
| Not draining | Dishwasher drain pump WPW10348269 | Pushes water out through the drain hose |
| Not starting / stops | Dishwasher door latch WPW10653840 | Confirms the door is closed so the control will run |
| Poor cleaning | Dishwasher spray arm WPW10491331 | Delivers wash water to dishes |
Catching the root cause early prevents repeat wash cycles, reduces detergent waste, and helps avoid water left in the tub that can lead to odors. The manual’s “problem solver” steps also cover normal pauses during washing and what to check when the unit stops. See the WDT780SAEM2 owner's manual for model-specific indicators and troubleshooting.

What model of Whirlpool dishwasher do I have?
Your Whirlpool dishwasher’s model number is printed on the rating label inside the tub, right near the door opening (on the right-hand or left-hand side). For your unit, you’re looking for a number formatted like WDT780SAEM2. See the exact label location in the WDT780SAEM2 user guide.
Open the door and look along the inner edge of the tub opening near the door. The label typically includes both the model number and serial number.
- Check the right-hand side of the interior near the door
- If not there, check the left-hand side near the door
- Use a flashlight; the print can be small
- Write down the model and serial exactly as shown
- Take a photo so you can zoom in later
Whirlpool dishwasher model numbers are usually a mix of letters and numbers (for example, WDT780SAEM2). That exact model number is what we use to match the correct parts, diagrams, and troubleshooting steps.
| Item on label | What it tells you | When you need it |
|---|---|---|
| Model number | The exact dishwasher design and parts fit | Ordering parts, finding diagrams, manuals |
| Serial number | Production details (build date/sequence) | Service calls, warranty, identifying revisions |
Using the correct model number prevents ordering the wrong Whirlpool dishwasher parts (like a door latch, drain pump, or rack adjuster) and helps you follow the right repair instructions for your exact configuration.
