E9
Mabe E9 on top-load washer: water fill or level fault
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Medium
Quick answer
Error code E9 on a Mabe top-load washer means the water inlet valves were energized for a set time with no change in water level detected. Open the supply taps, confirm household water pressure of 70 to 700 kPa (10.15 to 101.52 psi), clean the inlet filters and clear the volatile fault.
Safety first
Stop and check this first
- Never fill the washer manually with buckets or a hose to work around E9: the Kraken manual warns that manual filling can damage the water valves from dry operation or exceed the maximum level (equivalent to 17.5 inches of water column), triggering the drain pump and overflow fault E8.
- Always disconnect electrical power and shut off the water supply taps before removing the fill hoses, and never pull the control panel or move the pressure switch hose vertically or horizontally because tensioning it can damage the board-mounted pressure sensor.
Safe checks you can perform
- Open the supply taps and verify 70 to 700 kPa pressure for E9
- Flush the supply pipe and clean the inlet filters once a month
- Clear volatile fault E9 from the Kraken control panel

What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Pressure switch hose inspection and pressure sensor test t8
What they doThe technician inspects the pressure switch hose for pinches at the top cover grommet or trapped water, checks the tub for leaks and runs service test t8, which fills the tub to 2 inches of water column and displays the reading.
They must show youthe unpinched, dry pressure switch hose and the water-column reading on the display during test t8.
In writingfindings on the pressure hose and top grommet plus the water-column value recorded in test t8.
Cold and hot water valve tests t1 and t2 in Kraken service mode
What they doThe technician enters Kraken diagnostic mode and runs test t1 (cold water valve) and test t2 (hot water valve), each with a 60-second auto-shutoff, while inspecting connector J10 and valve solenoids.
They must show youwater entering the tub during diagnostic test t1 and test t2.
In writingthe results of tests t1 and t2, the condition of connector J10 and whether any inlet valve was replaced.
Pressure sensor voltage verification and control board replacement
What they doWith water in the basket, the technician checks whether the pressure switch output voltage matches the actual water level against Mabe's pressure table and, if out of specification, replaces the main control board that houses the integrated pressure sensor.
They must show youthe comparison between actual basket water level and pressure sensor output before replacing the board.
In writingthe integrated pressure sensor diagnosis, the washer serial number and the warranty on the replacement board.

Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Open the supply taps and verify 70 to 700 kPa pressure for E9
- Who:
- you, at the water taps behind the washer.
- How:
- confirm that water is present in the household pipe and that the cold (C) and hot (H) taps are open within Mabe's 70 to 700 kPa (10.15 to 101.52 psi) operating range. If you only have a cold water tap, cap the hot valve and set the temperature knob to Cold-Cold (Frío-Frío), or fit a Y-adapter to feed both inlets and select Warm (Tibio) to shorten fill time, never filling the washer manually.
- Result that matters:
- steady water flow with adequate pressure reaching the connected washer inlets.
- If a tap was shut or street water was off:
- open the tap or wait for normal pressure before clearing E9.
- If the taps are open with normal household pressure but little water enters:
- inspect the fill hoses and clean the inlet filters next.
- Evidence to keep:
- a photo of the rear hose setup (dual taps, capped hot inlet or Y-adapter) and a note on your home water supply.

Flush the supply pipe and clean the inlet filters once a month
- Who:
- you, with the water taps shut and the washer unplugged.
- How:
- disconnect electrical power, shut off the water taps and unscrew the factory fill hoses (avoid used or deteriorated hoses). Open the taps into a bucket for a few minutes to flush the pipe and confirm there are no obstructions, clean the 2 inlet filters and washers as Mabe recommends once a month, then retighten the hose couplings securely without leaks.
- Result that matters:
- flushed supply pipes, clean inlet filters and restored water flow to the valves.
- If sediment was restricting the pipe or filters:
- after reconnecting the hoses, clear E9 on the panel and test filling.
- If the filters and hoses were already clear and water still does not enter:
- run the volatile fault reset on the control panel.
- Evidence to keep:
- a photo of the 2 inlet filters and hose washers before and after cleaning.

Clear volatile fault E9 from the Kraken control panel
- Who:
- you, at the washer control panel.
- How:
- on Kraken 24 or 27 inch Digital models, press and hold the On/Off (Encender/Apagar) button for 3 seconds (on Kraken 27 Hybrid, press On/Off). On Kraken 24 or 27 inch Knob models or Kraken 24 Hybrid, turn the cycle knob to OFF (APAGADO) and press START/PAUSE (INICIO/PAUSA); then select a medium water level and start a cycle to verify filling.
- Result that matters:
- volatile code E9 clearing from the display or status LEDs and the tub filling to the target level.
- If the washer fills and completes the cycle:
- E9 was caused by a temporary water supply interruption.
- If code E9 returns during fill:
- do not remove the control console and book a fill diagnosis with Mabe's authorized service.
- Evidence to keep:
- a short video of the display or LEDs when resetting and how long into filling E9 reappears.

What it means
In Mabe's Kraken Top-Load Washer Service Manual (24 and 27 inch cabinets, 15 to 24 kg capacity, such as LMA75211WGAA00) and Kraken Digital 27 inch Service Manual (18 to 22 kg capacity, such as LMA78100WGAB00), volatile fault E9 appears when the water valves stay energized for a set period without the pressure sensor detecting the level change calculated by the control board. Other models may differ (knob models display faults as a binary LED combination), and code E9 alone never proves that a water valve, pressure sensor or control board is faulty.
Warnings and stop conditions
- Mediumeditorial warning
Never fill the washer manually with buckets or a hose to work around E9: the Kraken manual warns that manual filling can damage the water valves from dry operation or exceed the maximum level (equivalent to 17.5 inches of water column), triggering the drain pump and overflow fault E8.
Evidence: Mabe Ingenieria de Servicio - Manual de Servicio Lavadora Carga Superior Kraken (Junio 2016) · Mabe Ingenieria de Servicio - Manual de Servicio Lavadora Kraken Digital 27 pulgadas (Diciembre 2017)
- Loweditorial warning
Always disconnect electrical power and shut off the water supply taps before removing the fill hoses, and never pull the control panel or move the pressure switch hose vertically or horizontally because tensioning it can damage the board-mounted pressure sensor.

Symptoms and causes
Probable causes · in order
- No water in the supply line or pressure below 70 kPa (10.15 psi)Common
The Kraken fault table lists no water in the supply pipe as the primary cause of E9, along with household water pressure dropping below the 70 to 700 kPa (10.15 to 101.52 psi) design range and delaying tub fill.
Evidence: Mabe Ingenieria de Servicio - Manual de Servicio Lavadora Carga Superior Kraken (Junio 2016) · Mabe Ingenieria de Servicio - Manual de Servicio Lavadora Kraken Digital 27 pulgadas (Diciembre 2017)
- Disconnected fill hose or clogged inlet filter screensCommon
Mabe's Kraken service manual lists a disconnected supply hose as the second direct cause of E9, or restricted flow when the supply pipes were not flushed before installation and the 2 inlet filters are not cleaned once a month.
Evidence: Mabe Ingenieria de Servicio - Manual de Servicio Lavadora Carga Superior Kraken (Junio 2016) · Mabe Ingenieria de Servicio - Manual de Servicio Lavadora Kraken Digital 27 pulgadas (Diciembre 2017)
- Pinched pressure switch hose, trapped water or pressure leakPossible
According to the Kraken service manual, when the pressure switch reading lags behind the water volume calculated from valve-on time, the board assumes a pinch in the pressure hose near the top cover grommet, water trapped in that hose or a tub leak.
Evidence: Mabe Ingenieria de Servicio - Manual de Servicio Lavadora Carga Superior Kraken (Junio 2016) · Mabe Ingenieria de Servicio - Manual de Servicio Lavadora Kraken Digital 27 pulgadas (Diciembre 2017)
- Inoperative water valve or out-of-range pressure sensor on the boardLess common
Once external water supply and hoses are verified, the Kraken technical guide points to a water valve that fails to open or a pressure sensor output voltage on the main control board that does not match the actual basket water level.
