Do-it-yourself multicooker repair: the nuances and subtleties of the process

Most mod­ern house­wives know first­hand about the ben­e­fits and effec­tive­ness of Red­mond mul­ti­cook­ers. This ver­sa­tile kitchen appli­ance has made it pos­si­ble to pro­vide thou­sands of homes with healthy, nutri­tious, hot and deli­cious food. Any­one who has used this device at least once, in fact, was con­vinced of its effec­tive­ness. How­ev­er, like all elec­tri­cal appli­ances, it is sub­ject to var­i­ous break­downs. First of all, fail­ures in the oper­a­tion of the device are attrib­uted to a fac­to­ry defect. How­ev­er, some­times it hap­pens that the device breaks down dur­ing oper­a­tion. It was then that most peo­ple think about repair­ing a mul­ti­cook­er with their own hands. It is pos­si­ble to per­form it at home, but for this you will have to take into account sev­er­al nuances.

Operating requirements

To pro­tect the Red­mond mul­ti­cook­er from break­downs and not think about how to fix it your­self, you must fol­low the require­ments pre­scribed in the instruc­tions for the device.

The first step is to high­light the sequence of lay­ing prod­ucts before cook­ing. Before lay­ing the bowl for food must be removed from the Red­mond mul­ti­cook­er. Oth­er­wise:

• liq­uids poured into the bowl may inad­ver­tent­ly spill into the mech­a­nism;
• for­get­ting that the con­tain­er is on the table, you can start pour­ing liq­uid into the inside of the equip­ment, there­by drown­ing the mech­a­nisms or fill­ing them with bulk prod­ucts.

Common causes of damage to Redmond multicookers

Most mal­func­tions occur due to con­t­a­m­i­na­tion of the con­tacts of the device. This can be caused by liq­uid or loose prod­ucts enter­ing the inside of the device, such as:

• cere­als (rice, buck­wheat);
• sug­ar;
• salt.

This type of break­down is the most harm­less and it will be easy to repair mul­ti­cook­ers with your own hands. At the same time, it is worth remem­ber­ing that until the end of the process of clean­ing and assem­bling the struc­ture, the device should in no case be con­nect­ed to the net­work.

How to clean the Redmond multicooker?

To clean the device with your own hands, it is impor­tant to study and fol­low the sequence of actions.

1. Remove the met­al (plas­tic) cov­er, as well as oth­er vis­i­ble ele­ments attached with screws.
2. Clean the chips by turn­ing the instru­ment upside down and gen­tly shak­ing it off.
3. Attach the cov­er and oth­er top ele­ments.

In the case when the clogged con­tacts are locat­ed at the bot­tom of the device, it is nec­es­sary:

• unscrew the screws secur­ing the bot­tom cov­er;
• dis­con­nect the cables con­nect­ing the heat­ing and pro­gram­ming boards;
• remove the heat­ing ele­ment by unscrew­ing the screws;
• care­ful­ly remove the inter­nal ther­mome­ter with­out dam­ag­ing the device;
• clean chips and boards from bulk prod­ucts.

Fol­low­ing the dis­as­sem­bly rules, clean­ing the device will not cause much trou­ble.

Software errors of Redmond multicookers

In some cas­es, Red­mond mul­ti­cook­ers may stop work­ing, giv­ing a spe­cif­ic alphanu­mer­ic error code. The abil­i­ty to deci­pher the code will allow you to under­stand the cause of the break­down and begin to elim­i­nate it. Infor­ma­tion for decod­ing is known to man­u­fac­tur­ers, as well as crafts­men spe­cial­iz­ing in the repair of house­hold appli­ances.

Cer­tain errors dis­played on the screen sig­nal seri­ous mal­func­tions. Nev­er­the­less, there is a list of codes explored by ordi­nary users through tri­al and error.

Thus, crafts­men man­aged to find out that the mes­sage “e0-e4” dis­played on the screen indi­cates mal­func­tions asso­ci­at­ed with short cir­cuits, as well as breaks in tem­per­a­ture sen­sors locat­ed above or below. Also, the prob­lem may be relat­ed to ther­mal fus­es. Dif­fer­ent man­u­fac­tur­ers set their own codes, so for repairs on your own, you will need to remove the case of the device and use the capa­bil­i­ties of the mul­ti­me­ter to detect a break by mea­sur­ing the lev­el of con­tact resis­tance.

Anoth­er com­mon rea­son for which mul­ti­cook­er repairs may be required is a clogged ther­mo­stat respon­si­ble for heat­ing. In most cas­es, it is locat­ed at the bot­tom of the device, next to the pow­er board. To get to and repair the ther­mo­stat, you need to remove the bot­tom of the struc­ture. Before clean­ing, the cop­per con­tacts must be slight­ly unclenched, and then wiped with zero sand­pa­per or thick paper. The cause of such a break­down may be the accu­mu­la­tion of mois­ture that has pen­e­trat­ed into the mech­a­nism due to liq­uid spilled past the bowl. The for­ma­tion of con­den­sate is also pos­si­ble.

What is the function of a thermal fuse?

The ther­mal fuse for the mul­ti­cook­er is one of its most impor­tant parts. It is a small piece of wire, indis­tin­guish­able from a resis­tor. The con­duc­tiv­i­ty index is 10–15 A, based on the type of ele­ment. The high­est tem­per­a­ture is 150–170 degrees. Exceed­ing the per­mis­si­ble lim­its will lead to the fuse burn­ing and break­ing the elec­tri­cal cir­cuit, which can be deter­mined using a mul­ti­me­ter.

Finding and replacing a thermal fuse

The most impor­tant part of the Red­mond mul­ti­cook­er is locat­ed in the cen­ter of the device. Most mod­ern mod­els are equipped with sev­er­al ther­mal fus­es cov­ered with pro­tec­tive plas­tic insu­la­tion. To detect a blown fuse, it is nec­es­sary to dis­man­tle the bot­tom cov­er of the device.

After remov­ing the bowl, you can see the but­ton: out­ward­ly, the knot resem­bles a steel mush­room, the low­er part of which is cov­ered with a spring. The cir­cum­fer­en­tial sur­face is the heat­ing ele­ment of the Red­mond mul­ti­cook­er. The ther­mal fus­es are locat­ed near the main assem­bly.

In this case, the plas­tic insu­la­tion is vis­i­ble. Some man­u­fac­tur­ers secure them with clamps screwed to the screw, but in most cas­es, the fus­es sim­ply hang in the air.

Since the fus­es are fac­to­ry-mount­ed by crimp­ing, sol­der­ing is strict­ly pro­hib­it­ed, since a hot sol­der­ing iron can burn a heat-sen­si­tive fuse. To deter­mine which ele­ment is faulty, and whether at least one of them is work­ing, use a mul­ti­me­ter to mea­sure the resis­tance with­out remov­ing the fuse. After a mal­func­tion is detect­ed, the fuse must be replaced.

Microcircuits in modern Redmond multicookers

Mod­ern mul­ti­cook­ers are equipped with two elec­tron­ic boards:

• man­agers;
• pow­er.

The main board respon­si­ble for heat­ing is locat­ed at the bot­tom of the device, while the con­trol board is locat­ed in the heart of the device — inside the work­ing cylin­der.

Upon care­ful inspec­tion of the micro­cir­cuits, sev­er­al signs of prob­lems can be detect­ed:

• detach­ment of tracks;
• vio­la­tion of sol­der seams;
• black­en­ing of resis­tors;
• swelling of capac­i­tors;
• soot for­ma­tion.

If one of the items on the list is found, it is worth repair­ing or replac­ing parts, restor­ing the sol­der­ing or board tracks with the help of zero­ing skins and tin­ning the dam­aged areas. Jumpers can be made from burnt resis­tors using their legs. To fix the sol­der­ing and tracks, it is rec­om­mend­ed to use a var­nish that pro­tects the cir­cuit from leak­age and oxi­da­tion.
