美国采购需求：地下泵

I'm reaching out regarding the variable speed pump. It seems that the capacitor might not be functioning properly, and I'd like to gather more details on the issue. Could you provide specific insights into troubleshooting steps or potential replacements? Also, if there are any related documents or guides you could share, that would be really helpful. I'm looking to resolve this as quickly as possible, so any prompt feedback would be appreciated. Thanks!
