Water proof alarm
With that error code, taking off the top and front/side/back is very certainly worth the 15min.
And check around the door seal.
If the spider is starting to deteriorate, you could still have a few months of use to consider and order a replacement.
That error just means there is water detected by the float switch in the bottom of the machine.
That can get there on accident while cleaning out the pump trap or of course could stem from a hole in some pipeing in there somewhere.
Might be as simple as a hose clamp being loose.
You can remove the water usually by just tilting the machine forward to drain it up over out of the bottom pan.
Then with easy view on typical components start a cycle and see where the water might be coming from.
If it's just a 20$ part, you would have a lot more time to explore your options, budgets and requirements!
