  If the maximum flushing pressure isn't being reached on your Homburg Ultrasonic Jewelry Cleaner, it could be due to several reasons. The pump valves might not be closing properly, requiring a pump repair. Alternatively, the suction basket could be fouled and in need of cleaning. Check for leakage in the water pressure controller, and if found, replace the pressure plate or seat. Lastly, the nozzle might be worn, necessitating a replacement.

  An irregular pump suction in your Homburg Ultrasonic Jewelry Cleaner can stem from several causes. First, ensure the suction basket is fully submerged. If it is, check for any fouling and clean the basket if necessary. A defective suction basket connection would need repair. Other potential issues include pump valves not closing properly (requiring pump repair), incorrect pressure in the accumulator (adjust accumulator pressure), a leaking suction hose (replace the hose), or a leaking pump coupling (replace the O-washer or coupling).

  If your Homburg Ultrasonic Jewelry Cleaner pump is losing oil, it could be due to the oil level being too high; in that case, lower the oil level. Another possible cause is diaphragm failure, which would require pump repair.
