Miele dishwashers are German engineered and claim to perform flawlessly for at least twice the life of an average dishwasher. They have a reputation of reliability and durability and are safe for delicate china but powerful enough to clean dirty pots and pans. The Miele Novotronic G851SC dishwasher is solidly built and reputable but through general use an owner may occasionally run into some common problems. With the following instructions, minor problems can be fixed without a service call.
Load the dishes so that water can reach all surfaces. Rotate the spray arm manually to check the clearance; the arm should not be blocked with tall items. Scrape food from dishes before placing in the dishwasher. Each dish should have its own space and not be inside another dish. Place tall pieces in the centre of the lower basket and not in the corner.
Set the wash cycle appropriately by referring to the program guide in the owner's manual. Heavily soiled items need to be washed on a different setting than light to normally soiled dishes.
Use the correct detergent. Use only powder or tablets; gel or liquid detergents are not recommended. Do not use too much detergent -- two tablespoons of detergent is
adequate for most cycles. If the dishes are heavily soiled or have food stuck to them, use a prewash cycle and add one extra tablespoon of detergent to compartment I. With homes that have soft water, use less detergent.
Clean the spray arm jets, which may be clogged with particles of food. Turn off the dishwasher and remove the cutlery tray. Lift the top and middle spray arms up to engage the ratchet; unscrew both. Remove the lower basket and remove the lower spray arm by pulling it firmly upwards. Clean the jets with a toothpick or a pointed object. Rinse the arms thoroughly and return them to their places. Rotate them to be sure they have been inserted correctly.
Add a rinse aid before using the dishwasher for the first time and then again when the "Rinse aid" indicator light is lit. Rinse aid will help prevent white residue, clouding and spotting on the dishes.
Add reactivation salt to the reservoir before using the dishwasher for the first time and then whenever the "Salt-PC" indicator light is lit. When the reservoir is full, the water softener will activate when the dishwasher starts the next time. Do not use reactivation salt if your water is already soft.
Remove the lower basket to add the salt. Remove the salt reservoir cap located on the floor of the dishwasher. Use a funnel to fill the salt reservoir. Replace the cap correctly or the salt may leech out and cause spotting and cloudiness.
Clean the triple filter. Turn off the dishwasher before cleaning. Locate the filter in the bottom of the cabinet. Turn the handle counterclockwise and lift the filter out. Eliminate any particles of food. Rinse the filter with water and return it to the base of the cabinet. Do not run the dishwasher without the filter in place.
Check to see that the drain pump is not blocked. Turn off the dishwasher and remove the triple filter. Scoop the water out of the bottom. Tilt the locking clamp to one side and pull out the non-return valve. Rinse the valve to get rid of any food or residue. The drain pump is underneath the valve. Before putting the valve back into place, make sure that the drain pump is not obstructed. Spin the propeller in both directions. Return the valve and tighten the locking clamp. Refit and lock the filter in place.
Check the drain hose to make sure there are no kinks in it. This could cause the water to back up into the bottom of the cabinet.
If your troubleshooting efforts do not bring results, contact the Miele Technical Service Department at 1-800-999-1360 or by e-mail at firstname.lastname@example.org. Make sure to have your model and serial number ready. These are found on the inside upper edge of the door of the dishwasher.
