Hi Dave,
Does your machine look like this?
Amazon.com : Bosch Vision 500 Series DLX : WFVC6450UC 27 Front-Load Washer 4.4 cu. ft Capacity - White : Front Load Clothes Washing Machines : Appliances
If so its very similar to mine.
Boschョ 3.3 cu. Ft. Washer and 3.9 cu. Ft. Electric Dryer - White - Sears | Sears Canada however is is considerably larger..
I was warned to avoid the larger Boschs, particularly the Made in USA ones. Whats the COO of yours? Mines Made in Germany and is a full 220v unit.. Apparently they made the drum larger for the US market (Americans apparently wont buy small things, surprise!). My drum is only 3.3cuft, where the 500 model is 4.4cuft. Unfortunately making it larger also made it susceptible for other problems that the smaller ones didnt face (larger drum, more weight, therefore more load on components. Front loads were never designed to be "once a week" washers as is common in the US. They are designed to be daily washers, as is common in the EU). The salesman was really trying to push me into the larger model (same cost, more capacity and bells and whistles... Id be an
idiot for not getting it!) but I stuck to my guns.
Anyways, I digress.. lol.
On my model there is a door on the front to access the cleanout. There should be on yours too. You may have to remove the front panel though. Give a search over on ApplianceJunk.com. Theyre pretty helpful and you may be able to get the actual shop manual through them. Ive gotten my manuals for my Samsung appliances and my Bosch Wash and dry via AJ.
As to Persil. There is a product that a service guy recommended to use to clean up the spider and bacteria ( I didnt need it for my washer, but I had asked what he recommended for those complaining about smells). It was called Glisten. Id recommend using that as a starting point. If you have bacteria present, then you need to be rid of it. Persil by itself likely wont do that, but it will keep the residue down that allows it to grow, once you are rid of it. Leaving the door open can help too.
Have you seen the lawsuit over front loads? I wonder how much of those complaints are detergent/user caused vs. defective design? Some detergent types are well known to eat aluminum spiders.
