Eheim 2213 low flow problem
I woke up this morning to water trickling out of the spraybar on my Eheim 2213 (it's less than a year old). So, basically gutted it, rinsed the coarse pad which was gunked up, replaced the fine pad, cleaned the hoses, cleaned the spraybar, cleaned the impeller on the pump, and still the flow is about 1/3 to 1/4 what it should be, it improved a tiny bit after all this but not enough to make a big difference. I've also taken off the strainer on the intake and cleaned that as well. So my only guess is it's something within the top of the filter. Problem is I've never taken it apart, basically I don't go past the impeller. The diagram in the manual shows a different lid almost than what mine has. It has a part you have to pop off with a screwdriver, and I don't see that on mine. I'm going to wait til this afternoon to attempt to gut it but wasn't sure if folks could help maybe troubleshoot before I get into it or tell me what I need to look for that would cause the flow to be so reduced. Or help me figure out how to get it apart. Oh, and no kinks in the hoses, nothing has changed with the setup, the flow has been a little reduced over the last day or two but this morning it was just dribbling out of the spraybar.
