Water in both sinks are going down slow

[naveen]

Hi All,

I just had a question about something I noticed. Since last week my dishwasher is not working and beeping three time. According to internet this means that it means theres water in the base of the dishwasher activating the flood switch.
Funny enough water my sinks both in the kitchen AND the bathroom are going down very slow.
I wonder if this is related. If it is, there is no point calling a repairer for my dishwasher, right. Also, how can I fix this myself. Should I get a plumber?

Thanks,

Naveen
