BAD ODOR EMANATING FROM THE TUB
Bad Odor Issue
... potential risk of mildew build-up in front load washers.
Front load washers are designed for High Efficiency performance and as such utilize less water and
detergent and consume less power. Not unlike any other high performance equipment, greater care
is required to ensure optimized operability of these machines.
It has been observed and commented that some folks had encountered disagreeable experiences with
their front load washers, notably smelly odours escalating to mildew and mould. Due to the low level
of water utilized, wash residue such as grime, dirt, etc. along with detergents and softeners don’t
always drain completely out of the tub.
Residue can also accumulate in the rubber door gasket and over time mildew is formed. Mildew
develops on damp surfaces that have experienced water build-up that has not dried properly.
Mildew will start off as splotchy patches of black, green or white and later turn into mould if not
taken care of adequately.
In the same fashion as why dish detergent does not work well in a dishwasher which requires specially
formulated non-suds forming dishwasher detergent, front loading washer manufacturers all insist that
only High Efficiency detergent be used. Regular detergent in a front loading washer would produce way
too much suds causing delays and confusion in the washing cycles, making proper rinsing of clothes
rather impossible and diminish the washer’s capability at draining itself properly therefore inadvertently
setting up the stage for mildew building conditions.
High Efficiency, or HE, refers to a washing machine that uses 20 to 80 percent less water and
energy than standard washing machines. These are typically front-loaders. A logo with the letters
HE will appear on the front of detergent packaging suitable for a High Efficiency washing machine.
When you think about it, a High Efficiency front-loading washing machine utilizes up to 80% less
water than a conventional top load washer. Putting in the same amount of regular detergent that
would normally be required in a top loader would be 5 times too much in a front loading washer.
Compound to that the different gravitational pull while draining the wash residue and water, the
hermetical flawless design of the door and that has all the making of a disastrous outcome unless
good usage, care and maintenance are part of the laundry routine.
When buying a front-loader one should be prepared to give that washer a little extra care to
prevent such unfortunate situation by adhering to manufacturer recommendations regarding
running the cleaning cycle, using only HE detergents and following these below tips and to
prevent any issues from developing. The LG has a tub clean cycle and during this cycle it spends
a lot of time spraying water through the door seal area.
1. Powder HE soap seems to work best. Liquid soap does not break down in cold and warm
water. Powder soap breaks down better in any kind of water.
2. Always make sure to run hot cycles every now and then. Using only cold cycles causes mildew
and mould in the drain hoses and cold water doesn’t wash it out or break it down. Hot cycles
break down mildew and mould spores while keeping your unit clean.
3. Use a quarter cup of dish washing detergent (powder), along with a towel. Put the machine on
the "sanitary" (hottest water) setting. Let it finish its cycle. This should get rid of the mould
4. Use powdered bleach for colours and liquid bleach for whites, this helps to maintain the mould
5. Leave the door/lid (and the soap dispenser) open or slightly ajar between washes to let in fresh
air. Mould can only grow in stale air.
Does the washing machine drain completely? Is there any residual water in the tub after wash cycle
fully terminated? Inspect the drain hose to ensure no backflow. Could be a potential house piping
