HOSE

Part 02-3980-01 corresponds to the Multiple brands Hose, used in service situations where wear or damage is disrupting operation. Disconnect power before service. Reassemble so nothing pinches, rubs, or binds once the unit is back together. Once the root cause is corrected, performance should stabilize and output should return to normal. Tubes and connectors route water and drain flow. Splits, kinks, or loose connections lead to leaks or restricted distribution. Technicians typically replace this part when they’re seeing restricted flow, visible wear, cracking, corrosion, or a component that won’t stay seated. A good diagnostic approach is to confirm the symptom, then check mounting points and adjacent connections for contributing issues. Take a photo before disassembly so you can confirm orientation and fastener locations during reassembly.

If the part interacts with water, do a leak check during the first run and again after a short operating period.
