HW5513M Hoover washer dryer has a coin filter which I clean regularly, but washer door seal (and hence laundry) has wet fluff buildup. How do I prevent this?

The condenser coils are underneath and it the perfect place to attract fluff, especially if you have animals. On mine, you open the bottom door and pull off the kick grill. There is also a panel on the back at the bottom that hides the compressor. That is an easier place to get the vacuum cleaner crevice tool in. You buzzing may be overheating, but it may also be a sign of impending failure.

How To Clean Your Washing Machine Filter - YouTube

Cleaning the fluff filter and pump
Check the fluff filter initially after 3 - 4 washes to ascertain how often it is likely to require cleaning. With normal cleaning approx. 2 litres of water run out.

If the drain outlet is clogged, more water will be retained in the machine (up to 25 litres).

Caution: if laundry has been washed at a high temperature,
water draining out of the machine will still be hot!

Take the (yellow) filter flap opener from behind the detergent drawer facia panel. Open the flap.

Place a dish under the drain fixture. Turn the fluff filter lid round 2 - 3
times. Do not take it right out.

With large volumes of water when the dish is full, screw the fluff filter back into position and empty the dish before repeating the procedure.

Once the flow of water ceases, remove the fluff filter completely and
clean it.
Remove any foreign bodies (e.g. buttons, coins, etc.) and fluff.
Turn the impeller by hand to check that it is free to rotate. Any foreign objects causing an obstruction should be removed.

Clean the inside of the fluff filter housing. Remove any deposits of lime scale and detergent or foreign bodies from the thread of the filter housing and filter unit (as these objects can cause a leakage
of water). Put the fluff filter back and screw it in firmly.
Cleaning and care

To clean the water inlet filters
The washing machine has two filters to protect the inlet valves. These filters should be checked every 6 months or so, or more often if there are frequent interruptions to the water supply.

To clean the filter in the union in the open end of the inlet hose:
First turn off the stopcock.
Unscrew the threaded union connecting the free end of the inlet hose to the stopcock.
Remove the rubber seal from the recess. Using pointed pliers, take hold of the plastic filter bar, remove the filter and clean.

Put the filter and seal back in the reverse order and reconnect the
hose. Turn on the stopcock and check the connection is watertight.
Inspect the inlet hose which is subjected to high pressure while the machine is in operation. The hose should be replaced if there are small cracks in the surface, or if it has been otherwise damaged.

If replacing the inlet hose only use a hose able to withstand pressure up to 70 bar. Miele's own hoses meet this requirement.

To clean the filter in the water inlet valve:
Using pliers, carefully loosen the ribbed plastic nut on the inlet valve,
and unscrew.
Use water pump pliers to withdraw the plastic filter by the bar.
Clean, put back and secure.
The two filters must be put back in place after cleaning.

Drying consists of removing moisture through heat and airflow. Check to make sure that your venting tube is not kinked somewhere and therefore not allowing the air to flow freely from the dryer.

I am having the same problem on a WD9900A. The wash cycle works great. Spins fast and clothes are completely rung out. Dryer cycle heats up well. Fluffs and heats cloths. At some point during dry cycle water is injected on clothes and they end up sopping wet; much wetter than after wash. Filter is clear. Outlet pipe clear and functions well. Possible problem with dryer timer? Or washer timing kicking back on?

Make sure the lint trap in the door is clean. It has a plastic cover that opens. Disconnect the venting at the rear and run a load, if it works you have a restriction in the hose after the dryer or in the wall past the hose.
