Clean and Hygienic Linen:

The following points need to be considered for clean and hygiene linen.

Linen should be handled less in the process to avoid the spread of  contamination.  

Proportionate use of  detergents and whiteners, as per the load of linen, is advisable.

Access to use of detergent can lead to the detergent remaining on the linen and 

become  hard after the linen is dried.

Disinfectant chemicals are to be used in the wash cycle to disinfect the linen. Barrier 

 washers can be used to avoid the excessive handling of linen. 

Cleaning of Washing Machines and Dryers:

Washing machines from outside should be cleaned by lint free clothes dipped in purified and disinfected water. Inside the washing machine the drum must be wiped by a clean, soft, lint free cotton cloth.  

Before removing the filter from the washing machine, remove the main electrical plug from the switch board. Make sure the plug is placed in a safe position where it does not get wet. Keep an old towel or scraper to soak in the water before dismantling the filter from the machine.  

Locating the filter: 

For the front loaded washing machine, generally the filter is fitted outside the washing machine at the bottom on the right side.

Agitator is the device located in the center of the machine, that rotates to and forth during the washing cycle.

Filters need to be cleaned every 3 to 4 months. Remove the cover from the filter by pulling it away from the machine. Use thin objects like screw drivers to remove the cover. Once you hold the cover, rotate it anti clock wise to remove it.

If the filter is fitted below the agitator, then first remove the agitator. After removing the agitator, lift the filter cover out of position. Once you remove out the filter you will see a wet lint mixed with the remainder of the detergent. In some filters the drain hose is fitted before the filter. In that case you need to remove the drain hose first to take out the filter. Use a paper towel to remove lint from the filter. Residue on the filter is the mix of lint and detergent. Use clean tissue paper to wipe it off. Use a small brush to clean the board of the filters.

Remove the screen from the filter housing and immerse it in hot water for 10 minutes. Before replacing the filter, check inside the machine for any loose lint. If there is a lint in the drum, remove it or scrub it with a wet sponge.

Once it is cleaned, fit it back into place. If you have removed the hose or the agitator, then put it back into position and fix the filter. Then fill the washer with water, run is with-out load to check for the leakages if any.

Clean the filters at least every month regularly. Do not wait for your washer to decide to stop working in the middle of the washing cycle, to find out what is wrong with it. There are many signs you may miss that indicates the filter needs to be maintained.

If you notice excessive vibrations after the final spin, drainage problems, check the clogging of the filter or choking of the drain line. Neglecting the door seal during normal washing. If anything gets stuck in it can go and get trapped in the filter. It can clog the filter by becoming harder to clean and potentially reducing the life of the filter.
