Midea heat pump fault-code guide

Find the manufacturer label and copy the entire RSJ identifier, including slash, capacity digits and final suffix. The Australian distributor manuals captured here name RSJ-15/190RDN3-C in the HP170 publication and RSJ-23/300RDN3-B plus RSJ-23/300RDN3-C in the HP280 publication. Those exact strings, printed alongside the market product names, are the evidence bridge. “Midea heat pump” or “RSJ 300” is not specific enough. Photograph the serial number at the same time because both Midea’s customer-care process and the distributor service route need product identity to locate the correct warranty and technical record.

For the three sourced RSJ models, the relevant owner interface is the integrated controller documented in the Chromagen HP170 or HP280 manual. It presents operating settings and uses the same screen for fault or protection indications. Record whether the physical unit corresponds to the 170 or 280 manual, then photograph all characters and icons on the active display. Midea’s broader Australian range and support site cover many appliance categories, so an error observed on another Midea product cannot be imported into this water-heater namespace. The exact RSJ plate is what connects the screen to these captured tables.

The code meanings published for RSJ-15/190RDN3-C are anchored to the HP170 Version 1.3 table on page 22. The RSJ-23/300RDN3-B and -C meanings are anchored to the HP280 Version 2.2 table on page 20. Both tables expressly treat LA as a normal low-ambient condition for which repair is unnecessary, so LA is excluded from the fault pages. This demonstrates why status and fault rows require editorial review. Use the matching RSJ family, preserve the displayed form, and do not interpret a character through a generic internet list detached from these documents.

Midea’s current Australian product material describes error-code display capability but did not supply the code dictionary used here. The sourced rows instead come from official Chromagen Australia manuals that explicitly print both the Chromagen product and Midea RSJ model identifiers. That makes them suitable distributor evidence for those three records, not a manufacturer-wide Midea controller assertion. RSJ suffix variants elsewhere in the government register remain unmapped when absent from the manuals. Similar naming, tank size or shared OEM appearance cannot substitute for an official alias or controller-scope statement.

Midea Australia’s contact page provides a dedicated Hot Water Systems enquiry route and an Australian warranty-claim link. For a unit supplied through Chromagen, the official Chromagen heat-pump page publishes Midea warranty documents and a service-request route. Check the purchase invoice and installer paperwork to identify the responsible channel instead of sending parallel claims. Prepare the RSJ model, serial, installation date, proof of purchase, screen photograph and fault description. The relevant support team can then confirm the warranty terms, service agent and whether the observed condition belongs to the product or its installation.

What is public here is a precise cross-brand evidence chain: captured Australian distributor manuals name three Midea RSJ models, describe their controllers and expose literal code tables; Midea Australia separately maintains current customer-care and warranty-claim channels. What is not public is a universal Midea water-heater code dictionary that covers every registry identifier or firmware revision. This site labels the manual publisher and preserves exact scope so users can see that distinction. Unsupported Midea models receive no inferred meanings, even when their identifiers resemble the three covered RSJ units, because topical depth should not come at the cost of evidence accuracy.
