It is common for a fridge’s drain channels and drain hole/pipe to block with debris and ice, causing flooding in the fridge compartment during defrost cycles.
By specifying drainage requirements and providing clear cleaning instructions, blockages and flooding can be avoided.
The specification below provides the recommended improvements needed to improve product durability. They are ranked from bronze to gold based on the effectiveness of the change in improving durability, with bronze being the minimum and gold being the maximum.
Drainage channels to be smooth and appropriate dimensions
Drain moulding profile; anti-friction coating
Multi-air flow humidity control
Look at the drainage arrangements (channels, hole, pipe) to check that they meet the characteristics noted above.
Ask for clear evidence of meeting the requirements listed above, e.g.:
Improved reliability of components can reduce early returns and improve brand reputation which, in turn, can lower business costs and increase long-term sales.
To calculate overall cost savings for your business, use the WRAP cost/benefit analysis tool (currently in draft form and available on request).
Clear Instructions/Removable Sticker
Clear instructions will reduce the possibility of returns through user-error.
Simple inspection procedures will help to identify manufacturing faults and component issues, reduce failure rates and customer returns.
Including a cleaning plunger brush and instructions for its use will help the user to keep the drain hole clean.
Drain channels and drain hole – new profile
The interior liner of a fridge is normally a single piece moulding. It may be possible to modify the tooling to increase the drain hole aperture and shape of the drain channels.
New drain pipe
New drain pipe, clear of the rear moulding will help to reduce blockages.
Food grade anti-friction coating
A coating will help to keep the drain hole clean and reduce blockages.
Multi air flow humidity control
Multi-air-flow humidity-controlled fridges do not need a defrost cycle or a drain hole and provide more even overall cooling.
