How to remove front panel to access pump of Bosch VarioPerfect Serie|4 WAN24001GB/19

[Interactive]

I have the fluff filter open, I can see and touch the pump vanes and I can put my finger in the hole where the sump hose connects to the pump housing.

So here is the question I have been asking:
How do I test that there is no blockage in the sump hose (the hose from the drum to the pump)?

Can I do it by pouring water into the drum?

yes and no

if you pour water in it should come out almost immediately but when a machine pumps out its volume that counts so you can have a partial blockage and it still wont pump out in time

You`re over thinking this! To answer the question about a litre in the drum with all 4 feet on terra firma.
What you need to do is to remove the black sump hose off the tank via undoing the 7mm clip screw BUT before you do that I always got a marker pen and drew a line on the rubber to the plastic tank so you refit as it was. If you unscrew the clip and pull the hose off you`ll see the ping pong ball in the rubber hose and so long as nothing is lying ontop of it such as a colour catcher, bit of old sock…whatever? If you do not see anything you`ll need to stick your finger into the tank`s sump hose hole to make sure nothing is lying/trapped in the heater which from failing memory goes over the sump hose hole and so should you get a colour catcher that is where it ends up OR if luckier it lyes on top of the ping pong ball. This is the most commom place for no pump out/poor pump out on this machine other than a failed pump. Looking at the pump you have its part number for the model you state is 00146083 £39.25 from Bosch and has a light blue coloured filter handle. Your outlet hose is the type that is a push nozzle fit via an oil sealso no clip on that hose. Just double check there is not a 5p coin that hasn`t blocked it plus try to avoid taking off the drain hose off the pump as it is not overly easy to do that nor to refit it, but if a new drain hose is needed part number is 11017238 @ £7.39 which is surprisingly cheap from Bosch.
