It goes normally from the back right through to the front and is connected there

Error f21 happens when the machine does not drain in an appropriate time. This can be caused by a blockage in the drain or a faulty pump. There is a previous post in relation to resetting this error. have siemens washing machine that says f21 what does that mean

best i can do is google translate

F03 is
Drain alarm (water in the tank is reduced to one level in the allotted time plot )

you ran out of time for the drum to fill
{too low pressure}
use the hot water valve as the cold
block off the hot water intake
this way you have a low pressure valve for cold

1. There is a poor connection at terminals bilge pumps - seal the clamps, clean the terminals. 2. A malfunction in the bilge pump - clean the filter pump washing machine Siemens (Siemens) to either replace it. 3. There was a problem with the drain hose - hose to clean from pollution, eliminate the excesses, to restore the position of the drain hose specified in the instruction manual. 4. The pressure switch is faulty washing machine - repair of hydraulic water level sensor or replace the pressure switch.

My Siemens runs constantly, for hours, and doesn't drain all the water from the bottom. Is this also a "clogged drain" issue or is there something else wrong?

It is a common fault that the drain fails to work in most machines in a period of time and is the most problematic fault in a dish-washing machine. In all occasions it is important that your observation is most important and so is vital to the identification /rectification and solution. In some cases the drain hose would be clogged at the drain end to outlet of the house and so there will be back flushing resulting in overflow to the outside. Also the drain pump/valve can be clogged. Now remove the drain hose clamps and remove the drain pump/valve, clean the drain pump/valve, use back flushing to clear off all dirt. Now test using power to see if this works and can be simulated. When refitting, the hose must be tightened properly. If the pump/valve does not work even with power then it must be replaced. If there is intermittent power to the drain valve/pump then the program controller unit is a suspect.

Cleaning a pump:

Finally the washer must be placed with a tilt- use a spirit level- so that all water will drain to the outlet port and thereby there is no residual water remaining.

Dishwasher Problems - Waterwill not drain out

Hello & Welcome to FixYa

Dishwasher not draining completely problem usually occurs due to clogged/blocked drain hose or the drain pump not working. First try to clean the drain hose and drain pump filter for any clogs, then check drain pump operation. If the problem returns after cleaning then it is the drain pump that needs replacement. Please get back to me if you have any other questions.

get another hose same diamiter and two hose clamps and a splice nipple from hardware store, cut hose to lenght with some extra insert nipple into both hoses and clamp with hose clamps make sure you get them tight.. use a metal nipple as a plastic one may crack when you clamp hoses

www.apdepot.com
they are very reasonably priced. If you don't find the part on their website, call them.
I just purchased that same part (drain pump assembly) for about $ 63.
Now I have to find out how to access it to replace it!!
