“It seems as if the draining is happening super often (every 5-10min) and is extremely loud. Is that normal? Is there anything I could do with the drain pipe and where it's going to reduce noise?”

Hello there. Thank you for sharing your experience with us. We understand that your LG 24" Front Control Built-In Tub Dishwasher (LDFN4542S) seems to be draining frequently and loudly. While some noises during dishwasher operation are normal, frequent and extremely loud draining every 5-10 minutes is not typical. This could indicate a few things: Clogged Drain Filter: A common cause of rattling or excessive noise during draining can be a loose or clogged drain filter. We recommend checking and cleaning the drain filter at the bottom of the dishwasher. Drain Pipe Obstruction: Food waste or other foreign objects can gather and clog the drain pipe, leading to loud gulping sounds. You might consider checking if the drainpipe (which connects to your sink drain or garbage disposal) is clear of obstructions or kinks. Water Pressure: Sometimes, a high-pitched whistling or loud water noise can be due to high water pressure. While this typically relates to water filling, it's worth noting if the sound is more of a whistling during draining. Drain Pump Issue: If the noise is a high-pitched whining or grinding, it could suggest an issue with the drain pump itself. Regarding reducing noise from the drain pipe, ensuring the drain hose is installed correctly and without kinks, and confirming that the air gap (if present) is clear can sometimes help. Some users also look into insulation around the drain pipe for noise dampening, but the primary focus should be on resolving the underlying cause of the frequent and loud draining. https://www.lg.com/us/support/help-library/lg-dishwasher-common-noises--20151094805351 Your feedback is important, and we'd like to assist you further.
