Cleaning Sub-Zero Drip Pan: Easy Steps To Follow

Keeping your Sub-Zero drip pan clean is essential for maintaining your refrigerator's performance and preventing water leaks. The drip pan, also known as the drain pan, collects condensate liquid as a normal part of the refrigeration process. While it doesn't need to be emptied regularly, it should be cleaned occasionally to prevent overflow and potential damage. The cleaning process involves removing the pan, emptying any liquid, and using a mild detergent, baking soda paste, and water to wipe it down before rinsing and drying. For certain Sub-Zero models, additional steps may be required, such as removing the kickplate and using a turkey baster to remove excess water. It's important to refer to the specific instructions for your Sub-Zero model to ensure safe and effective cleaning of the drip pan.

How to Clean a Sub-Zero Drip Pan

Removing the drip pan

To remove the drip pan from a Sub-Zero refrigerator, you will first need to turn off the refrigerator at the unit On/Off button or by turning the control dial down past 1 to OFF. Next, remove the kickplate by unscrewing the two screws at the bottom left and right corners and pulling it forward.

The exact steps to remove the drip pan will depend on the model of your Sub-Zero refrigerator.

601, 501, and 201 Models

Remove the lower grille by unscrewing the screws on the right and left corners, then pull the bottom of the grille out and up to release it.

500 Series Models

Push the front of the drain pan back and down, then pull the drain pan forward.

Classic (BI) and PRO Series Models

Push the front of the drain pan up slightly, then pull it forward.

600 Series, Designer Series (IT, IC, ID), and 700 Series Models

The drip pan is not removable by the consumer for these models. Contact Factory Certified Service for drain pan removal if needed.

Cleaning the drip pan

The drip pan is located at the bottom of the unit and collects condensate liquid as part of the normal refrigeration process. It is normal for the drip pan to be half-full of water at any given time, and this condensation will evaporate as the unit runs, so it is not necessary to empty it regularly.

However, if the drip pan does overflow, it will need to be cleaned. To clean the drip pan of a Sub-Zero refrigerator:

• Remove the kickplate by unscrewing the two screws at the bottom left and right corners and pulling it forward.
• Remove the drip pan by pushing it up slightly and then pulling it forward.
• Empty the drip pan.
• Clean the drip pan with a mild detergent, baking soda paste, and water, wiping it with a soft cloth. Rinse and dry thoroughly.
• Reinstall the drip pan by sliding it into the front of the unit on the two side brackets. Push the drip pan in and up slightly until it stops.
• Reattach the kickplate by screwing it into place.

If you have a Sub-Zero 501, 601, or 201 model, you will also need to remove the lower grille by unscrewing the corners and pulling the bottom of the grille out and up to release it.

For the 500 Series, after removing the kickplate, push the front of the drain pan back and down before pulling it forward. To reinstall, insert the tapered end of the drain pan into the drain pan holder at the rear, ensuring the tapered ends with cut corners face toward the rear of the unit on the wire support bracket. Then, push the front of the drain pan up until the top front flange engages the tab in the kickplate support.

If you have a 700 Series or Designer Series product, the drip pan is not accessible and cannot be removed for cleaning. Contact Factory Certified Service for drain pan removal if needed.

Reinstalling the drip pan

Classic (BI) and PRO Series

• To install, slide the drain pan in from the front of the unit on the two side brackets. Push the drain pan in and up slightly until it stops. You will feel it lock into place.
• Reattach the kickplate by screwing in the two screws at the bottom left and right corners.

500 Series

• Insert the tapered end of the drain pan into the drain pan holder at the rear. The tapered ends with cut corners face toward the rear of the unit on the wire support bracket. The square end of the drain pan is the front.
• Push the front of the drain pan up until the top front flange engages the tab in the kickplate support.
• Reattach the kickplate by screwing in the two screws at the bottom left and right corners.

For other models, refer to the specific guides for the 600 Series, 200, 501, and 601 Models, and the Designer Series (IT, IC, ID) and 700 Series. If you are unsure about the model or require further assistance, contact the Sub-Zero Customer Care team.

When to contact a professional

While cleaning a Sub-Zero drip pan is a relatively straightforward process, there are several instances where it is best to contact a professional for assistance.

Firstly, if your Sub-Zero unit is part of the Designer Series (IT, IC, ID) or 700 Series, the drip pan is not accessible for removal or cleaning. In such cases, it is necessary to contact Factory Certified Service for any required maintenance or repairs. They will have the expertise and tools to safely access and service the drip pan.

Secondly, if you encounter any issues with the kickplate removal process, it is advisable to seek professional help. The kickplate is typically removed by unscrewing two screws at the bottom left and right corners and then pulling it forward. However, if you are unable to locate the screws or safely remove the kickplate, a professional will be able to assist without causing any damage to your unit.

Additionally, if your drip pan fills up with water quickly and frequently, it may indicate a more complex issue. While some factors such as temperature settings, defrost cycles, food storage, and room humidity can contribute to water accumulation, persistent overflow could signal a problem with the sealed system or a lack of condenser cleaning. In such cases, contacting a certified technician is recommended to diagnose and rectify the issue.

Finally, if you are experiencing any other issues with your Sub-Zero unit, such as clogged drain tubes, poor temperatures, or door sealing problems, it is best to engage Factory Certified Service. They will be able to provide specialised advice and repairs to address the specific challenges you are facing with your appliance.

While basic cleaning and maintenance can be handled by following the manufacturer's guidelines, it is always best to seek professional assistance for complex issues to ensure the continued safe and efficient operation of your Sub-Zero appliance.

Water in the drain pan

It is normal for water to be in the drain pan, and the amount of water can vary depending on humidity, temperature, and how often the unit is running. Drain pans can be half-full regularly without issue, and the condensation will evaporate as the unit runs, so it is not necessary to empty it regularly. However, if the drain pan is overflowing, contact Factory Certified Service for a repair.
