Why is my Labconco Dishwasher not drying properly?
- T
  Tina GarciaAug 16, 2025
  Poor drying results from several potential issues. The drying temperature might be too low, so you should program a warmer drying temperature. Improper loading of flasks, beakers, or labware can also cause this; ensure these items are tilted to allow water to drain. Recondensation can occur, so open the latch after the cycle to let moisture escape. Other causes include disconnected or malfunctioning heaters or blowers (reconnect or replace them, respectively), dry time being too short (program a longer time), or a temperature sensor that is out of calibration (verify the displayed temperature with a thermocouple; if it differs by more than ±4°C, contact Labconco Product Services).

  If your Labconco Dishwasher is not draining, there are several possible causes: 1. The drain might be clogged, so clean it out. 2. The air gap could be blocked; clean it by lifting the cover, unscrewing the cap, and removing any debris. 3. There might be a kink in the drain hose, so check for that. 4. The filter could be blocked; check the filter in the washer and clean it as needed. 5. The drain valve or pump might not be operating; check their operation.

Why is my Labconco Dishwasher leaking?

  Jason ThompsonAug 26, 2025
  If your Labconco Dishwasher is leaking, several issues could be the cause. First, ensure the washer is level by adjusting the leveling feet. Check if the door is sealing properly and adjust the door latch if necessary. Inspect the tank gasket for looseness and correct it. Tighten any loose connections at hose clamps or at the fill valve. Using an improper amount of detergent can also cause leaks, so use a non-foaming detergent and the proper amount. An obstruction in the drain line or the washer overfilling could also lead to leaks, so remove any obstruction and check the operation of the fill switch.

  If the selection buttons on your Labconco Dishwasher control panel are inoperable, it could be due to a microprocessor memory error. In this case, perform a "Factory Reset." Open the latch on the door, press the ? button, and simultaneously close the door latch. Release the ? button, and the display will show the setup screen. Press ? until FACTORY RESET is highlighted, then press ? or ? until “Yes” is displayed, and finally press RUN. Alternatively, the keypad might be defective, in which case it should be replaced.
