Hotpoint Fridge Freezer Problems

Hotpoint fridge freezers are known for their durability and quality. However, as with any household appliance, they can face issues over time. A common problem experienced by users of certain Hotpoint models, like the FFUD3 k, relates to ice build-up and a malfunctioning fan. Let’s delve into the problem and its solutions.

The Problem:

Owners of the Hotpoint FFUD3 k frost-free fridge freezer have reported unexpected noises, particularly a cracking sound. On investigation, this noise is often attributed to the evaporator fan. Over time, some users have observed excessive icing, particularly in the freezer compartment, despite it being a frost-free model. This has been notably prominent in the upper front drawer and the roof and rear areas of the freezer.

Potential Causes & Solutions:

1. Evaporator Fan Malfunction:
   • Cause: The noise, followed by the freezer’s cooling inefficiency, can be attributed to the evaporator fan malfunction.
   • Solution: While some initially speculate that the fan might be obstructed by ice, this isn’t always the case. However, you can check the fan’s resistance using a meter. It’s essential to remember that the fan might only get powered when the door is closed. If the fan is catching onto something, it could be solid ice, pointing to a bigger issue.
2. Air Channel Blockages:
   • Cause: Excessive ice formation in the air channels may be a consequence of the freezer door being left open inadvertently. This allows moist air to enter, leading to the build-up of ice, which can obstruct the cold air flow channels.
   • Solution: A practical approach to address this is to:
     • Remove the rear panel of the freezer to access the evaporator fan.
     • Look for any visible ice blockages. One user reported discovering a solid block of ice below the evaporator fan, blocking all cold air flow channels.
     • Use a hairdryer to melt the ice and restore cold air flow. Ensure that all moisture is removed to prevent future blockages.
3. Polystyrene Back Panel Modification:
   • Cause: Behind the freezer’s rear panel, there’s a polystyrene layer with channels. The original design might allow water droplets to pool and freeze during the auto de-ice mode.
   • Solution: To address this:
     • Remove the freezer’s rear panel.
     • Separate the polystyrene and the plastic panel.
     • Modify the polystyrene channels to ensure that moisture/droplets fall into the freezer’s bottom, preventing them from freezing inside the polystyrene. This modification involves extending the existing channels in the polystyrene to redirect the water flow.
     • Some users have also added duct tape to the polystyrene’s surface, making it less porous and minimizing ice crystal formation. Additionally, applying a hydrophobic layer can further reduce moisture and ice build-up.

General Tips:

• Always ensure that the freezer door is securely closed to prevent moist air from entering.
• If you notice issues with cooling or excessive ice build-up, inspect the cold air flow channels and the evaporator fan promptly.
• Conduct regular maintenance checks and consider modifications, as mentioned, to enhance the freezer’s performance.

Conclusion:

While the Hotpoint fridge freezer is an efficient appliance, the ice build-up issue can be a challenge. Understanding the problem and implementing the outlined solutions can ensure that your fridge freezer functions optimally for years to come. As always, when in doubt, consult with a professional.
