How to fix a computer board on a hoshizaki Ice Machine with a three beeps mode

[@darinruddock3394]

My “3 Beep” Problem Solved. My ice guide (the plastic screen that lays under the evaporator), had several pieces of plastic that broken off and were missing. I thought, “where did they go?” They had fallen into the reservoir. Some pieces passed through the pump, over time, and had been pumped UP and were sitting in the water spray guides ON TOP, of the evaporator. BUT, a few pieces did not get pumped up with the water. They were in the pump, slowing the flow, (which I suspect was a several month long problem I had with very slow production of ice). Eventually, one of the pieces jammed in the pump, stopped the pump, and triggered the “3 BEEP”. I took off the pump, cleared the little pieces of plastic out of the impellers, and it’s working like new. Visually inspect your Ice Guide, if it has pieces missing, they are likely causing slow water flow in the water lines somewhere, and maybe even have the pump jammed.

first make sure al the lines are frozen within 15 minutes, second check the float for any calcium, with the machine on off position make sure you are not getting water from the water valve, those are the most common symptoms, but if it works fine for several hours or even days more likely is going to be the circuit board also check water pump. please let me know if this advice was helpful. thanks

Leo have you taken a few of those relays apart to see the cause of failure. If pitted contacts they could be sanded or filled to get the resturaunt by when one doesnt have a spare.

[@leodepena]

I don't think you can open it, because is all sealed

[@jpp9876]

@@leodepena thanks for this video, one thing you may want to pick up is a solder sucker. They use them in stained glass work.

Great video! Will be looking at other vids if you have up. I have an am150 and the condenser fan and water pump both stop working together. They are getting power and the capacitor for the water pump is within range. Is it circuit board replacement time? Thanks

[@leodepena]

If you are getting 120 volts to the pump and condenser fan motor, more likely are bad.

I would like to purchase that relay kit. I have a KM-501MAH with a failing bottom relay...

[@purrungas2012]

Thanks for your video, very to the point, I got the 2 beeps hot gas coil ok, thermistor ok, will check my board tomorrow, will this work for the HGV ? Thanks again

Excellent video I'm going to try right away thank you

Oiga Leo buenas tardes mire este Disculpe la molestia ya reemplace la válvula de agua y sigo teniendo el mismo problema lo que he notado Es que la flota nunca sube ni baja siempre está Al mismo nivel solamente que vacié toda el agua baja pero si está lleno el tanque se está un solo nivel

Mr pena When any led its on in the board and the machine just working in wash mode and dont working in ice mode

[@satberhoxhaj3347]

i have an old hoshizaki ice machine and it just started giving me 3 beeps any idea what i should change first??? thanks

[@javieroliveros3964]

Mr. Peña, Do you have any information regarding the one beep? or any other tricks that would work to solve the issue? Gracias y saludos!

[@leodepena]

One beep mode means thermistor is sensing high temperature, that's the one that has two orange wires, follow the wires and touch the copper line right where is attached to the copper line to make sure is not warm, and if it is it could be because hot water is entering to the ice machine, second thing, check the solenoid gas valve to make sure is not leaking hot gas, but if is leaking hot gas usually the machine will take a long time to freeze causing the alarm to go in to three beeps, and the last thing to check is the thermistor, I had several bad thermistors that causes to enter in a one beep mode. if that's the case unplug the thermistor, and it should work temporarily, check the thermistor for continuity it should reed 3.9 k at 48 degrees, please let me know if this was helpful.

[@javieroliveros3964]

In my training, I was told that it was mostly hot water entering the machine, and the second most common reason was inadequate ventilation. just wanted to double check. next time I am working with one beeps I'll check the thermistor to the board. thanks for the tip. quite helpful !!

You are welcome

Hi, Leo I have KM-515MWH. Serial number #E04818E. My control board is 2A3792-01. My problem is LED 4 is not on. I want to change the relay for Led 4 but I couldn’t find it anywhere. Can you tell me how I can find the relay for Led #4? Thanks,

Cuál es el relay de válvula de agua no me manda voltaje a la valvula la tarjeta...si le llega 220 pero no me manda a la valvula ..a los demas componentes si pero no inicia la secuencia....le puse 115volt directo a la valvula y si trabaja pero no manda señal a pompa y si le presiono el test machine si prende todo menos la valvula y al ponerla directa no manda señal latarjeta a la bomba tengo pensado poner nueva tarjeta que me recomienda Saludos desde austin tx mi makina es una hoshisaki board hos2a1410-02

[@galdinodejesus4482]

My ice machine had the same issue 3 beeps. The compressor works but the water from inlet valve doesn't stop

[@leodepena]

Turn off the machine and look at outlet of the water valve and if is still leaking, the water valve needs to be replaced, what happens is because you getting fresh water and it will take forever to make the ice, and before that happens it will go in to a 3 beep mode

[@SAMMY23MIAMI]

Hey leo. Thanks for the awesome video. Can please give me the part number for the relay?

Coal es el hot gas valve relay. Bien video.

[@leodepena]

El primer relay es el de hot gas valve

[@jose-if6zv]

Tengo una maquina hoshisaki no me manda power a la válvula de agua ...le puse 115 volt directo a la válvula y si prende ......a los demas componentes si les manda voltaje xq le puse en test machine y prende pompa y la refrigeracion....en wash si lo hace pero en ice no manda voltaje a válvula agua la cale directa si prendio pero ahora no me manda señal a la bomba ..que relay sería de la tarjeta o como arreglarla estot apunto de comprar una en 150 pero queria saber sonde y como consigo los relay Saludos desde austin tx

[@leodepena]

@@jose-if6zv Revisa primero el flotador porque es el que le manda la señal al computer board y de allí a la válvula, suerte y saludos

[@tino12345ize]

Hola lío Cómo está Mire yo ya le hice todo eso a mi máquina también tengo una dosis aquí y ya le cambié el flotador ya el hice limpieza general

[@tino12345ize]

Gracias por tomarse el tiempo de contestar mi pregunta Leo este mire si yo creo que va a ser el la válvula del agua porque estoy mirando el flotador y nunca baja siempre está en un nivel de agua como si siempre estuviera lleno el tanque

[@tino12345ize]

Y la flota también es nueva

[@leodepena]

Revisa la Mangera negra donde sienta el flotador porque a veces se tapa de calcio

[@tino12345ize]

@@leodepena sí ya también la quité

[@tino12345ize]

La limpié volví a lavar todo otra vez y sigue igual Sabrá Dios que tendrá

Excelente ! Gracias

[@tino12345ize]

Y aún así sigue haciendo los 3 pitidos yo no tengo problema con el compresor Porque si enciende bien Lo único que tienes que tarda mucho en congelar y pasa la hora y empieza a sonar los tres pititos famosos

[@leodepena]

Los tres pitidos es cuando la maquina tarda más de una hora en hacer el hielo, entonces tienes otro problema, apaga la maquina y asegúrate que no esta pasando agua por la valvula porque eso hace que la maquina tarde más en hacer el hielo

[@brianjohnson9067]

better then prying and poking out the hole after use wick to remove solder and re-solder new one in

[@SoutheastHVAC]

The ice machine I’m working on is tied into a rack 🙄

[@leodepena]

How many beeps are you having
