Spider corrosion To vacfanatic, Thank you for posting the photographs of the various spiders. I find them quite informative. Please would you mind answering a few easy questions? 1. On post 465688 (the first one). Do you have any idea what the white substance showing in the centre of the spider...

Spider Corrosion To favorit. Thank you for your thoughts and comments. Let us take this one step at a time. Yes rinses do dilute chemicals the more times you ‘rinse’ the weaker the concentration of remaining chemicals become: except of course for the chemicals and suspended solids in the...

Bosch's Answer I have now received a letter response from Bosch. I will précis the main points of the letter. Should anyone want a copy drop me an email and I will scan it and forward a copy. The letter makes no reference to the emails from the technician so we must assume that they are...

Bosch's Replies - Well Sort Of After two e-mail attempts elicited no response from Bosch, I tried the telephone and reached a lady in the greater Montreal area. The exchange of e-mails that resulted is copied below. As I consider these unsatisfactory answers I tried ¡®snail mail¡¯, again...

Apology It has come to, my attention that there is an error in the final line of my post on 23 July 2010. The last line should read: - Anyone know where there is more information on the decomposition of sodium hypochlorite at temperatures above 104F? My apologies for any inconveniences or...

Whirlpool's Response-Or Lack Thereof At my second attempt I have received a response from Whirlpool reproduced below, together with a copy of my communication to them Dear Mr. XXXXX, Thank you for visiting the Whirlpool web site. We appreciate hearing from you. Please accept our apologies...

Metal Fatigue & Low Temperature Performance Of Aluminium To Malcolm – mrb627 Thank you for your input. I believe what is commonly called ‘metal fatigue’ is very likely the ultimate cause of the vast majority of catastrophic spider failures. I believe it is generally described as the failure of...

To Jetcone, surgilator and mark_wpduet First Jetcone Since my response to you on 6 July, post number 447448, I have found, and read, a paper by one Gaute Svenningsen on the corrosion of aluminium. I found it very interesting in that it is the first time I have found any reference to the...

Spider Corrosion To sudsman It seems obvious to me that you have not read my posts on this thread, or if you have you have, you comprehend little of what I am saying. From my first post I have stated that for the corrosion to occur the pH of the ‘water’ remaining after the last spin will have...

Spider Corrosion To sudsman Should it not be LCB then what is causing the corrosion of the aluminium spiders? Please do not forget that I believe that any laundry aid with the potential to reach a pH above about 8.0 could cause corrosion of the spiders. Please let me have your thoughts and...

Decomposition of Sodium Hypochlorite (Bleach) To sudsman and Iheartmaytag. On thinking about your posts I started to wonder, ‘Over what temperature range is bleach effective?’ The information I have so far been able to glean is that it starts to slowly decompose when heated above 104F (40C) and...

Corrosion & Bleach ToIheartmaytag Thank you for the input it is duly noted. Bleach is corrosive at lower (cold tap) temperatures so once introduced into the machine the potential for corrosion of aluminium components exists, until such time as all traces of it, or any other additive which has...

Bosch Washers And LCB To foraloysius Thank you I missed that one. I have now downloaded the manual for the Vison 800 Series. This manual contains the following: - On page 2 Under the heading ‘3-Part Detergent Jet Dispenser’ the statement ‘A 3-part dispenser automatically distributes detergent...

Bosch Washers and LCB It is interesting to note that combo52 has dropped the temperature for the production of hazardous fumes from 200F to over 150F. A pity he did not enlighten us as to why! I have been unable to find any manuals, or indeed any relevant details for the two machines combo52...

FOCA Laundry Aid To Amyswasher Thank you for your input. I am not familiar with the FOCA detergent but reading other posts it seems as though it is ‘high sudsing’ and likely to contain phosphates. When did this incident take place? Similarly I am not familiar with the design of the LG’s spider...

Spider Corrosion Certainly seems possible. Proctor and Gamble’s MSDS for one of their powder ‘Tides’ gives the pH as 11.0. That level of alkalinity would not do an aluminium spider any good. Even with the Duet’s ‘suds killing’ program I believe sufficient would be left up near the hub to cause...

Temperature In Bosch Washers To combo52 I omitted this in the post above. In the manuals for the two named machines the maximum temperature setting available is 'Power Temp. Boost' at 160F. Neither manual makes any mention of a sanitizing cycle or anything similar.

Bosch Washer Manuals To combo52 I have downloaded manuals for Bosch washers WLF 2090 and WLF 2050 I would suggest that you do the same, or at least peruse them ‘on the web’. For the WLF 2090 machine the manual contains the following:- On page 5 under the Heading ‘IMPORTANT SAFETY INSTRUCTIONS’...

Got To Agree - Gud Numbers To Jetcone Just wish I had been as lucky

Spider Corrosion The following message has been sent to ‘combo52’ on thread number 29564 ‘Uh-Oh The Dreaded Bearing Roar Has Commenced’. I reproduce it on this thread as I believe it is also relevant here. "Thank you for your input. I found an owners manual for a Bosch Axxis on the web. At...
