may be too
old. Its effectiveness can deteriorate with time.
box of crystal detergent small enough to be consumed within 2 to 3 months of
normal dishwasher operation. Unlike other detergents, dishwasher detergent has a shelf life.
It can go
stale if kept too long. If you are consuming it within 3 months then look
for alternate reasons for poor cleaning.
it in a warm, dry environment. If possible keep in a sealed container. If
detergent picks up moisture it will become hardened, which can make it less
effective. Hardened detergent can cause poor cleaning plus problems for the detergent dispenser.
See question about poor cleaning.

Door - banging into counter
If the door is banging into
counter top try adjusting the feet.
The counter top may be swelling. Poor installation may be allowing steam from vent to hit the
counter top, causing it to swell. Check by using a straight edge along bottom
of counter top.
have moved on floor. This can allow body of
dishwasher to move out of alignment with side panels.
temperature - is it important
dishwashers require water temperature of approximately 120 to 140 degrees
Fahrenheit. Lower temperature can cause poor cleaning. If water
temperature is too low it cannot interact properly with the detergent to
clean the dishes.
Test the water temperature by running water in kitchen sink
for one minute. Then check using a thermometer. If water takes a long time to heat
this indicates your water tank is distant from kitchen area.
If hot water takes more than 5
seconds to reach maximum use a method called "pre-purging".
Pre -purging the hot water line means
Turn on hot water tap nearest dishwasher (usually kitchen sink) until the hottest water is
present. Run water until steam effect begins, then run few more seconds.
When hot water present at kitchen
sink turn off tap and start dishwasher.
Using this method will purge the cold water from the hot water pipes and allow hot
water to enter during the start of the wash cycle.
Also remember, the detergent may be dispensed
any time during the wash cycle, not just the beginning. Therefore having hot water
during the full cycle is required for proper cleaning.
White spots or grit on the glasses is often from lack of rinse additive.
Check your additive level regularly. Open door during wash to see if upper
spray arm is turning.
droplets on glasses
Check rinse additive level. The
additive is what allows the water to run off the items quickly at the end of
the cycle. Remember to turn glassware top downward when washing so water
will run out. Also items such as plastic plates will
retain more water droplets because of their porous material.
has rust colour
Can often be removed by the use of GLISTEN
cleaner. Most interior staining is caused by the minerals in your water.
Products like Glisten break down mineral deposits and wash them away.
Usually found in the detergent section of the grocery store.
has pink colour
A pink discolouring inside a dishwasher can be
due to cleaning large amounts of dishware that have contained a
tomato-based residue. The pink or red colour from the tomato-based food
residue can impregnate the pores of the dishwasher cabinet. This can usually
be removed by doing a number of hot washes without dishes inside. A product
such as Glisten may have to be also used, or a 1/4 cup of vinegar added to
the wash water to help break down the staining in the cabinet.
Check if a knife or
spoon has slipped out the bottom of the utensil holder and is hitting the
spray arm as it rotates. Also check if pots banging into other items.
Re-distribute items within dishwasher and restart.
Check the gasket at the bottom of the door for a build-up
of grease or debris. Also check filters. A buildup of food or grease on the
gasket bottom or in filters can cause odours. If necessary clean away debris
using a light detergent and
a non-abrasive sponge.
- plugs up with debris
Check plates for
debris before placing into dishwasher. Common to find items such as
toothpicks, fruit pits, pieces of plastic, child utensils, and food wrap. If you consistently find non-food debris in
the filters then more diligence will be necessary to stop this from occurring.
Leaking water from
the door? Check the door gasket for a hole or split. Also check the rotation
holes in the end of the spray arm because dirt here can cause leaks. Old, stale,
detergent can also cause leaks. Using detergent not made specifically for
dishwashers can cause this problems. Make sure machine is level - if too
low at front water can leak out beneath door. Use the detergent dispenser - too
much detergent can cause over sudsing, resulting in leakage.
racks are an indication of the plastic being scraped from the tines. Pushing
large items between tines can cause them to break or become damaged. A tine repair kit
is available to correct small amounts of rust. If tines
are broken off the rack will need to be replaced.
Rack difficult to pull out
Check for worn or broken wheels. If racks overloaded can also cause rack
to bent and jam against interior walls. If wheels do not rotate well do not
lubricate. Replace them. When pulling out the racks pull from the centre front
area of rack. If you pull from the side the rack can twist and jam against
the interior walls.
level is very low on some new style dishwashers. Some use 25% of that required
by older models. This is a big saving of water. Check your Use and Care manual (or
contact manufacturer) to determine what is a normal water level.
The down side
is that these machines must have water hot enough (minimum 125 degrees F) to wash
properly. The setting of your hot water tank may have to be raised to
provide these machines with sufficient hot water temperatures.
Check if high heat setting is being used. Using the
high heat setting can extend the cycle time drastically. The machine must
keep stopping to heat the water inside the cabinet to the proper wash temperature.
warmer function does exactly as the name implies. It will warm your plates
so that food can be served just like they do at a fancy restaurant. Great for a buffet, party,
or family function. Plus great way to impress the in-laws.
dry-heat dry switch will turn the heating element on or off during the drying section of
the cycle. The dishes can dry quite well without the use of added heat. So
if not in a hurry simply allow to air dry and save electricity. To speed up
this process open the door when the cycle is complete. This will let
the steam and excess moisture escape, and hasten drying.
are some dishwasher interiors metal while others are plastic
North American dishwashers use a plastic interior. This results in a lower cost, weight, and
operating sound level. North American homes have hot water storage tanks,
therefore the hot water required is pre-heated before entering the dishwasher .
Conversely, European dishwashers use metal interiors primarily
because they don't have hot water storage tanks. Their dishwashers fill with
cold water and then heat up the water while inside the dishwasher cabinet.
Heating up the water internally requires a metal
interior and a more complex design. The metal interior design is also noisy because the water is hitting metal as it
circulates during the cleaning cycle. To compensate for higher noise levels additional amounts of sound absorbing
insulation are added to the cabinet. These additional materials add to the overall price.
