Use this guide to enter diagnostic (self-test) mode on Speed Queen FF7 and TR7 series washers, run built-in component checks, and access the internal tech sheet for error code and test references. It also shows how to access and adjust the hidden DIP switches, including the extra-water setting on FF7 models.

ШагиSteps

Prepare the washer safely

Unplug the washer from the wall outlet.
Wait about 30 seconds, and plug the washer back in.
WARNING: Unplug the washer before removing panels or touching any wiring.
Caution: Keep hands, hair, and loose clothing away from moving parts during spin and agitation tests.

Understand how diagnostic commands are entered

Wait for the washer to finish booting, and leave it on the last mode it used.
Enter diagnostic commands by pressing two specific keys at the same time.
FF7 and TR7 use similar interfaces, but the key numbering can differ slightly between models.
Tip: If a command won’t start, power-cycle the washer again and try within five minutes of booting.

Enter factory test mode on an FF7

Start the factory test within five minutes of plugging the washer back in.
Press the Temperature key and the Whites key at the same time.
Confirm the display shows "FL" to indicate factory test mode has started.
This key combo is Temperature (key 2) + Whites (key 7) on the demonstrated FF7 panel.

Complete the keypad test stage

When the display shows the "P" keypad test, press every key on the control panel at least once.
Watch the display and indicator lights to confirm each key press is detected.
Press the Start key after you’ve pressed every key to conclude the keypad test.

Cycle door or lid switch checks and advance tests

Use the door closed or door open checks by opening and closing the door to change the sensed state.
Use the Start/Pause key to cycle certain checks when the test allows it.
Press the Start key to advance through many factory test stages.
Some stages won’t advance with Start, and require a condition to be met instead of a button press.

Run fill and water-level controlled stages

Let the washer run the fill stage that stops only when the pressure sensor reaches its target level.
Don’t expect the Start key to stop this fill stage while it’s filling to the pressure-sensor target.
Caution: Filling can be very loud, and water will enter the tub during this test.
Models with a heater may use a heater stage around test 14, and models without a heater may skip it automatically.

Finish spin and agitation stages and exit factory test

Let the washer drain, and allow it to advance into spin automatically after draining completes.
Read the RPM value as tens on the display until you advance to the following stage.
Use the breakaway agitate stage by opening the door when prompted, since this stage unlocks the door and uses a door-open action to advance.
Unplug the washer to exit the final factory test screen, since the controls won’t exit normally at the end of the sequence.
WARNING: The washer can appear “locked out” at the end of factory test, and unplugging is the only exit method described for that final stage.

Access the internal tech sheet and schematics

Use a 5/16 inch nut driver to remove the two screws at the rear of the top cover.
Slide the top cover toward the rear of the washer, and lift it off.
Locate the internal paperwork and schematics inside the cabinet, and use them for error code and diagnostic references.
Reminder: Reinstall the cover before running any moving tests if the cabinet edges are exposed.

Remove the FF7 control panel to reach the DIP switches

Unplug the washer before accessing the rear side of the control interface.
Use a 5/16 inch nut driver to remove the four screws along the top of the control panel.
Use a long 5/16 inch nut driver from the rear to remove the two hidden screws securing the bottom of the interface to the chassis.
Lift the panel up and away from the front of the washer.
Disconnect the interface wire harness if you need more room to reach the DIP switches.

Identify and change FF7 DIP switch settings

Find the bank of eight DIP switches on the interface board, located around the middle upper area of the board.
Take a photo of the original DIP switch positions before changing anything.
Set DIP switch 2 to ON to turn off energy-saving water and fill levels.
Set DIP switch 3 to ON to allow extra-water programming, which still requires a separate programming step at the UI.
WARNING: Changing DIP switches is a major modification, may affect warranty coverage, and some switches may not work on every model.

Program the FF7 extra water level after enabling DIP switch 3

Reinstall the control panel enough to use the controls safely, and plug the washer back in.
Press key 8 and key 14 at the same time to enter extra-water programming mode.
Press key 3 to increase the extra-water setting shown on the display.
Choose from 00, 05, 10, 15, or 20, and stop when the desired value is displayed.
These values represent extra water added per wash, where 20 means 2.0 inches, and the setting cycles back to 00 after 20.
Tip: Use the key-number chart in the internal tech sheet to identify the physical buttons for keys 3, 8, and 14 on your exact panel.

Run factory test mode on a TR7 and note the differences

Unplug the TR7, wait about 30 seconds, plug it back in, and start factory test within five minutes of booting.
Enter factory test using the same “press two keys at once” method used on the FF7.
Lift the lid, rather than opening a door outward, when a stage requires a lid or door change to advance.
Agitation-related stages will differ because the TR7 is a top-load design.
Advancing through stages is generally similar, using Start/Pause for many steps and letting valves or pumps run when required.

Access TR7 DIP switches and understand related settings

Locate the TR7 DIP switches on the interface board, since the board layout and DIP switch placement are described as similar to the FF7.
Look for three or four Torx screws along the top of the TR7 control panel, remove them, and roll the panel forward to access the interface.
Control panel attachment methods can vary, so use the internal tech sheet if the panel doesn’t match this description.
Use DIP switch 2 and DIP switch 3 as the key feature switches referenced for TR7 programming.
These settings are described as enabling changes like spray rinse versus tub-fill rinse, and additional water-temperature and fill-level programming.

Troubleshoot common problems during diagnostics and DIP programming

If the washer won’t enter factory test, unplug it for about 30 seconds, plug it in, and try again within five minutes of booting.
If a test won’t advance, watch for conditions like a required door or lid change, or a stage that must run until a sensor target is reached.
If the washer appears stuck at the end of factory test, unplug it to exit the mode.
If extra-water programming won’t appear, confirm DIP switch 3 is ON and use the internal key-number chart to verify you’re pressing the correct keys.
Reminder: If DIP switch changes cause unexpected behavior, restore the original switch positions using the photo you took.

Exit diagnostics and restore the washer to the ready state before returning it to service. Repair didn't go as planned? Ask our Answers community for help.
