Frigidaire Dishwasher: water not draining

What is this symptom?

If your Frigidaire dishwasher is not draining properly, you may notice water pooling at the bottom after a cycle. This issue often arises during the wash or rinse phases when water should be expelled. Several common causes could be at play, including a clogged filter, a kinked drain hose, or a faulty drain pump. Identifying the root cause can help restore proper drainage and keep your dishwasher functioning efficiently.
