Maytag Smart Dishwasher: Extra Dry Setting Not Working

Troubleshoot why the Extra Dry setting isn't working on your Maytag Smart Dishwasher. Expert diagnostics and solutions for Canadian homes.

Frequently Asked Questions

•What is the typical resistance range for a Maytag dishwasher heating element?

Generally, between 15-20 ohms, but refer to the specific model's service manual for accurate specifications.

•Where is the vent system usually located on a Maytag Smart Dishwasher?

Typically located near the door or on the side of the unit. Refer to the user manual for exact location.

•What is a safe RSSI value for stable Wi-Fi connectivity with a smart appliance?

An RSSI value above -70 dBm is generally considered acceptable for stable connectivity. A value closer to 0 dBm is better.

Technical Overview:

The "Extra Dry" function typically involves an increased heating element activation period during the drying cycle and potentially increased fan activity (if equipped). The dishwasher control board manages the heating element via a relay, and the smart functionality communicates cycle parameters to this control board via Wi-Fi (2.4 GHz) and potentially local communication protocols. Temperature sensors provide feedback to the control board to regulate the drying temperature. System relies on 120V AC power for control circuits and 240V AC for heating element.

Technical Recommendation:

Many Maytag dishwashers have a diagnostic mode accessible through a specific button sequence (consult the service manual). This mode can display error codes not visible during normal operation and can provide insights into component failures.

Recommended Action:

1

Power cycle the dishwasher by disconnecting it from the electrical outlet or tripping the breaker for 5 minutes.
2

Inspect the heating element for visible damage (burn marks, breaks). Use a multimeter to test its resistance (should be within manufacturer's specifications, usually around 15-20 ohms). Ensure breaker is locked out for safety during this step.
3

Check the thermistor's resistance using a multimeter at room temperature and compare it to the manufacturer's specifications. Replace if out of range.
4

Examine the control board for any signs of burnt components or damaged relays. If suspected, replace the control board.
5

Update the dishwasher's firmware to the latest version via the Maytag app. If the update fails, check your Wi-Fi signal strength (RSSI) near the dishwasher using a Wi-Fi analyzer app. A value below -70 dBm indicates a weak signal and potential update issues. Consider relocating your Wi-Fi router or adding a Wi-Fi extender.
6

Clear any obstructions from the dishwasher's vent system (usually located near the door or on the side of the unit).
7

Perform a factory reset of the dishwasher. Consult the user manual for specific instructions. Note that this may require reconnecting to the Maytag app and re-entering network credentials. Verify compatibility with your ISP’s settings (Bell Giga Hub, Rogers Ignite).

Observed Symptoms:

The "Extra Dry" setting, selected via the dishwasher's control panel or mobile app, does not result in adequately dried dishes after the wash cycle completes. Visual inspection may show condensation remains on dishes and the dishwasher interior. No error codes are displayed on the dishwasher panel or within the Maytag app; cycle completes normally according to timers.

Why This Happens:

Heating element failure or degradation, reducing its ability to generate sufficient heat.
Thermistor malfunction, providing inaccurate temperature readings to the control board, preventing optimal heating.
Relay failure on the control board, preventing the heating element from receiving power during the "Extra Dry" cycle.
Firmware bug affecting the "Extra Dry" setting's parameters (duration, temperature target).
Partial blockage in the vent system, inhibiting moisture release and reducing drying efficiency.
Wi-Fi connectivity issues between the dishwasher and the Maytag server, leading to incorrect cycle programming.

Preventative Care:

Regularly clean the dishwasher's filter to prevent blockages.
Run a dishwasher cleaner cycle monthly to remove mineral buildup.
Periodically check for firmware updates via the Maytag app.
Ensure the dishwasher has a stable Wi-Fi connection to receive updates and function optimally.
If living in a hard water area, use a water softener or rinse aid to prevent mineral deposits on the heating element and other components.
